Hyacine Planar Ornament Substats: HP% vs Healing Guide

Giant Tree of Rapt Brooding Mechanics

Giant Tree 2-piece provides +6% Speed baseline, scaling to +12% Outgoing Healing at 135+ Speed and +20% Outgoing Healing at 180+ Speed. Both wearer and memosprite Little Ica benefit from these bonuses.

Hyacine's Level 80 base stats: 1086 HP, 110 Speed. Target thresholds: 4500+ HP, 200+ Speed. The 200 Speed breakpoint unlocks Tempestuous Halt's bonuses: +20% Max HP and +1% Outgoing Healing per Speed point above 200, capping at +200% Outgoing Healing.

Mandatory Main Stats

• Body: Outgoing Healing Boost (only sustain option)
• Feet: Speed (required for 200+ breakpoint)
• Planar Sphere: HP% (43.2% max for 5-star)
• Link Rope: Energy Regeneration Rate (optimal) or HP% (acceptable)

This locks in substantial Outgoing Healing from Body slot, making additional Healing% substats less impactful than HP%.

Substat Roll Mechanics

Each 5-star ornament gains substats at +3, +6, +9, +12, +15. HP% rolls 3.4-4.4% per enhancement (22% max across five rolls). Speed adds +2 per roll. Outgoing Healing appears less frequently with smaller gains.

Key insight: Giant Tree already provides 20% Outgoing Healing at 180+ Speed plus Body slot bonus. Marginal value of extra Healing% diminishes rapidly. HP% substats simultaneously increase effective HP (reducing one-shot risk) and boost healing for HP-scaling abilities.

HP% vs Outgoing Healing: Math Comparison

HP% scales multiplicatively with base HP and all HP% bonuses from main stats, traces, Light Cones. For 1086 base HP, Planar Sphere's 43.2% HP% adds 469 HP. Each 4.4% HP% substat adds ~48 HP before Tempestuous Halt's +20% Max HP bonus at 200+ Speed.

Outgoing Healing Bonus applies additively to all healing. Stacks with 20% from Giant Tree (180+ Speed), 34.5% Body slot main stat, and Tempestuous Halt's potential +200% at max Speed.

Effective Healing Output

Baseline healing ability restoring 500 HP:

• 20% Giant Tree + 34.5% Body + 10% substats: 500 × 2.645 = 1,322 HP
• 20% Giant Tree + 34.5% Body + 0% substats but +20% HP%: 500 × 2.545 = 1,272 HP, but character has 20% more Max HP

50 HP difference (3.8% less) becomes negligible when character survives extra hits. In Apocalyptic Shadow Stage 4, Steadfast Safeguard reduces enemy damage by 50% until Weakness Broken—sustaining prolonged fights matters more than peak healing per turn.

Break-Even Analysis

HP% outperforms when:

• Team reaches healing sufficiency (no deaths from sustained damage)
• Enemy burst damage approaches character Max HP
• Abilities scale with Max HP (common for Abundance)
• Speed investment provides 180%+ Outgoing Healing from Tempestuous Halt

Outgoing Healing gains value when:

• Team takes consistent chip damage requiring frequent small heals
• Character has extremely low base HP (rare for Abundance)
• Healing abilities have fixed values unaffected by HP scaling
• Speed below 200 (missing Tempestuous Halt bonuses)

For F2P teams (Evernight Trailblazer, Cyrene, Hyacine, Castorice), Speed-focused build with HP% substats performs better across varied content.

Apocalyptic Shadow Stage 4 Requirements

Current Gale of Netherveil phase (2025-11-10 to 2025-12-22) Stage 4 Difficulty 4 requires 60,000 points for max rewards. Node 1: Sky-Shrouding Stardevourer Swarm (Quantum/Imaginary/Physical/Ice weak). Node 2: Opportunistic Provocateur (Wind/Lightning/Imaginary/Fire weak).

Steadfast Safeguard reduces enemy damage by 50% until Weakness Broken. Breaks dispel ally control, grant immediate actions, restore HP. Ruinous Ember buffs increase Memosprite Skill damage +15%, Ultimate damage +25%.

Damage Patterns

Difficulty 4 introduces Insect Egg Fission—enemies gain Eggs at turn end, Egg Burst produces more Eggs. Phase 2 spawns have +20% Max HP, extending fights and increasing cumulative damage.

Average team damage: 2,000-3,500 HP per cycle (500-875 HP healing per character per turn needed). With Giant Tree's 20% Outgoing Healing and Body bonuses, base healing abilities exceed thresholds, making extra Healing% redundant while HP% prevents sudden deaths.

One-Shot Prevention

Elite attacks deal 1,800-2,400 single-target damage, AoE hits for 1,200-1,600 per character. Characters with 4,500 HP survive two consecutive hits; 3,600 HP risks death before healing resolves.

HP% advantage: 4,500 HP with moderate healing outlasts 3,800 HP with 15% more Outgoing Healing. Dead characters contribute zero healing—survivability prerequisite for healing effectiveness.

F2P Abundance Character Optimization

Natasha: HP% Scaling Specialist

Natasha's healing scales directly with Max HP. Ultimate restores HP equal to percentage of her Max HP to all allies—every 1% HP increase = 1% more healing before Outgoing Healing multipliers.

Optimal substats:

1. Speed to 200+ (Tempestuous Halt bonuses)
2. HP% on every roll after Speed met
3. Energy Regeneration Rate for Ultimate uptime
4. Outgoing Healing only if no HP%/ERR available

With Planar Sphere HP% (43.2%) and five HP% substat rolls averaging 4% (20% total), Natasha reaches ~5,200 HP before Tempestuous Halt's +20%, scaling to 6,240 HP. This increases healing more than equivalent Outgoing Healing substats while providing survivability.

Lynx: Balanced Shield and Heal

Lynx provides shields and healing, both scaling from Max HP. HP% substats strengthen shields (preventing damage, reducing healing needs) and increase healing output. Defensive layering makes HP% ~40% more valuable than equivalent Outgoing Healing.

Technique restores 30% Max HP + 600 to allies. At 5,000 HP: 2,100 HP healed. At 4,000 HP: 1,800 HP. The 300 HP difference (16.7% more) from HP investment matches 16.7% Outgoing Healing substats, but HP% also strengthens shields and survivability.

Gallagher: Break Effect Considerations

Gallagher incorporates Break Effect scaling. E1 (not F2P accessible) provides +50% Max HP during After Rain, amplifying HP% value.

F2P priority:

1. Speed to 200+ (Tempestuous Halt)
2. Break Effect to 150%+ (core kit)
3. HP% for remaining slots
4. Energy Regeneration Rate if Ultimate uptime issues

Break Effect requirement doesn't eliminate HP% value—it competes for slots. Since Giant Tree provides substantial Outgoing Healing, HP% remains third priority after Speed and Break Effect.

Optimal Substat Rolling Strategy

F2P players face Trailblaze Power constraints limiting daily farming to 4-6 Cavern of Corrosion runs.

Priority Tiers

Tier 1 (Must Have): Speed substats until 200+ total. Every piece contributes Speed rolls until breakpoint unlocks Tempestuous Halt (+20% Max HP, up to +200% Outgoing Healing).

Tier 2 (High Value): Energy Regeneration Rate ensuring Ultimate every 2-3 turns. Abundance Ultimates provide team-wide healing or buffs critical for Stage 4.

Tier 3 (Core Stat): HP% on all remaining rolls. Dual benefits (healing + survivability) without diminishing returns until extreme HP (7,000+).

Tier 4 (Acceptable Filler): Outgoing Healing Bonus when HP% unavailable. Functional but mathematically inferior.

Tier 5 (Minimal Value): DEF%. Contributes negligibly to sustain vs HP%.

When to Stop Rolling

Planar Sphere with Speed +10, HP% +12%, ERR +5% = excellent stopping point. Further farming for Speed +12, HP% +16% yields marginal gains (3-5% performance) requiring dozens more runs.

If current substats enable Stage 4 clears with 55,000+ points, investing 20+ Trailblaze Power refills (800+ Stellar Jade) for 58,000 points = poor ROI. Redirect resources to secondary characters or other sets.

Accept pieces meeting:

• Planar Sphere: Speed +6+, HP% +8%+
• Link Rope: Speed +6+, ERR +3%+
• Any piece with three Tier 1-3 substats = good enough

Trailblaze Power Investment

Each run costs 40 Trailblaze Power, yields 2-3 pieces. Obtaining Planar Sphere with correct main stat (HP%) requires 8-12 runs (320-480 Power). Rolling to +15 with favorable substats averages 25-40 total pieces (400-640 Power for complete set).

Daily regeneration (240) supports 6 runs—complete optimized set requires 4-7 days dedicated farming. Spreading across 2-3 weeks while farming other sets provides better account progression.

Common Optimization Mistakes

Overvaluing Outgoing Healing at Speed Expense

Most frequent error: accepting Outgoing Healing substats on pieces lacking Speed, rationalizing more healing is always better. Speed serves triple duty: more frequent actions (more healing instances), unlocking Giant Tree's 20% at 180+, activating Tempestuous Halt's massive bonuses at 200+.

Outgoing Healing +12% but Speed +0 underperforms Speed +10, HP% +8% by ~25% total sustain value. Healing per action increases slightly, but reduced action frequency and missing set bonuses create net negative.

Ignoring Energy Regeneration Rate

Abundance Ultimates provide team-wide healing, cleansing, damage buffs critical for Stage 4. Characters with 100% ERR use Ultimates every 2-3 turns; 120%+ achieves every 2 turns consistently.

Hyacine's recommended Link Rope (ERR) addresses this, but substats matter with HP% Link Rope alternatives. 0% ERR substats delays Ultimates to every 4-5 turns, creating healing gaps causing wipes despite high per-action healing.

Neglecting Team Damage Reduction Synergies

Abundance characters don't operate isolated. Teams with Evernight Trailblazer or Cyrene gain damage reduction buffs decreasing healing requirements. In these comps, HP% preventing one-shots matters more than Outgoing Healing addressing chip damage already mitigated.

Teams lacking defensive buffs require higher healing throughput, slightly increasing Outgoing Healing value. Even then, HP% dual functionality (survivability + healing) maintains superiority until extreme HP where diminishing returns emerge.

Practical Testing Methodology

Theoretical calculations provide frameworks, but individual variables (Light Cone, teammates, skill) require empirical testing.

Measuring Healing Sufficiency

Run Stage 4 with current build and track:

• Deaths per attempt: Zero deaths across 3+ attempts = healing sufficiency achieved
• Lowest HP values: Characters consistently below 30% HP = increase healing or HP pools
• Unused healing: Characters above 80% HP most turns = healing overcapped, reallocate to Speed or damage

If teams clear consistently without deaths, current Outgoing Healing suffices. Extra Healing% provides zero value; prioritize HP% for safety margins.

Comparing Substat Distributions

Test two builds:

• Build A: Speed 205, HP 4,800, Outgoing Healing +55% (set + main + substats)
• Build B: Speed 205, HP 5,400, Outgoing Healing +45% (set + main only)

Run each through 5 Stage 4 attempts, record:

• Average clear time
• Total deaths
• Turns to stabilize HP after burst damage

Build B typically shows 5-10% slower clears but 40-60% fewer deaths, resulting in higher average points. Reliability gain outweighs marginal speed loss for consistent reward acquisition.

Light Cone Adjustments

Premium Light Cones (Quid Pro Quo, Post-Op Conversation) provide ERR or healing bonuses, reducing substat pressure. F2P options (Shared Feeling) require higher ERR substats for Ultimate uptime.

Test with your Light Cone:

• Ultimate every 2-3 turns without ERR substats = prioritize HP% heavily
• Ultimate delayed to 4+ turns = sacrifice one HP% slot for ERR
• Healing barely sufficient = consider one Outgoing Healing piece (but Speed and HP% first)

Long-Term Investment Value

Cavern of Corrosion farming for Giant Tree provides excellent long-term value. Set benefits all Abundance characters and many Harmony supports requiring Speed breakpoints—universal investment.

Farming Route Efficiency

Prioritize Hyacine when:

• Building first Abundance for endgame
• Current sets lack Speed substats preventing 200+ breakpoints
• Apocalyptic Shadow emphasizes sustain (current Gale of Netherveil)

Delay when:

• Abundance already clears content consistently
• Damage dealers lack proper sets
• Alternative sets provide greater account-wide improvement

Apocalyptic Shadow resets every 6 weeks (Monday 04:00 server time). Farm Hyacine during first 2-3 weeks of each phase, pivot to damage sets once sustain met.

Future-Proofing

New Abundance characters follow similar priorities: Speed for action frequency, HP% for scaling, ERR for Ultimate uptime. Hyacine pieces with Speed and HP% transfer seamlessly between characters.

Invest in 2-3 complete sets:

• Set 1: Max Speed (210+) for fast cycling supports
• Set 2: Balanced Speed (200-205) with high HP% for primary healers
• Set 3: Speed (180-190) with ERR focus for Ultimate-dependent characters

Initial investment (1,200-1,800 Trailblaze Power) pays dividends across multiple patches and releases.

When to Farm Hyacine vs Other Sets

Allocate ~30% ornament farming to Hyacine if running Abundance regularly. Remaining 70% targets damage sets (Rutilant Arena, Celestial Differentiator) for primary dealers.

Exception: struggling to clear Stage 4 due to sustain = temporarily increase Hyacine farming to 50-60% until consistent clears. Reward difference between Stage 3 and 4 (~200 Stellar Jade per cycle) justifies short-term focus.

FAQ

What's the difference between HP% and Outgoing Healing Bonus on Hyacine ornaments?

HP% increases Max HP pool, improving survivability and scaling HP-based healing abilities. Outgoing Healing Bonus multiplies healing output but provides no defense. With Giant Tree at 200+ Speed providing up to 220% Outgoing Healing (20% set + up to 200% Tempestuous Halt), extra Healing% substats are less valuable than HP% serving dual purposes.

Which Hyacine substats should F2P prioritize for Abundance?

Speed substats until 200+ total to unlock Tempestuous Halt bonuses. After Speed, HP% provides superior value over Outgoing Healing due to dual scaling (healing + survivability). Energy Regeneration Rate ranks third for Ultimate uptime. Only accept Outgoing Healing when HP% or ERR unavailable.

Does HP% or Outgoing Healing help more in Apocalyptic Shadow Stage 4?

HP% typically provides greater value. Prolonged fights with Steadfast Safeguard create scenarios where preventing one-shots matters as much as healing throughput. Characters with 4,500+ HP survive burst patterns killing 3,800 HP characters regardless of healing. Giant Tree and Body slot already provide 54.5%+ Outgoing Healing—extra Healing% shows diminishing returns while HP% maintains linear benefits.

How much HP% do Abundance healers need for endgame?

Target 4,500-5,500 HP for reliable Stage 4 performance. Requires HP% Planar Sphere (43.2%) plus 12-20% from substats. Combined with Tempestuous Halt's +20% at 200+ Speed, reaches ~5,400-6,600 total HP. Values above 6,000 HP show diminishing returns—additional investment less efficient than improving other team members.

Is Outgoing Healing Bonus worth farming on Hyacine?

Acceptable but not worth specifically farming. Giant Tree provides 20% at 180+ Speed, Body slot adds 34.5%, Tempestuous Halt contributes up to 200% at max Speed. Total 254.5% before substats—extra Healing% provides marginal gains. Accept when it appears, but prioritize Speed and HP% during farming. Don't reroll pieces lacking Healing% if other substats strong.

Should I reroll Hyacine pieces without Speed substats?

Yes, reroll Planar Sphere and Link Rope lacking Speed unless exceptional HP% and ERR rolls (16%+ HP and 8%+ ERR combined). Speed mandatory for 200+ breakpoint unlocking Tempestuous Halt's transformative bonuses. Perfect HP% and Outgoing Healing but zero Speed contributes less than Speed +10 with moderate HP%—Speed is non-negotiable foundation.
