Why Is the Blood Strike 7DS Collab Reward System So Generous — and What's the Catch?
The free track is genuinely stacked. Officially confirmed free rewards include:
| Reward | Method | Deadline |
|---|---|---|
| QBZ95 – Coffin of Eternal Darkness | Daily play/login tasks | May 3, 2026 |
| AK47 – Sacred Axe Rhitta (ultra skin) | Invite 3 friends | April 19, 2026 |
| Kar98k – Double Bow Harlit | 18 cumulative login days | May 3, 2026 |
| M700 skin | Event tasks | May 3, 2026 |
| Playpal – Hawk | Login rewards | May 3, 2026 |
| Playpal – Oslo | Play rewards | May 3, 2026 |
| Limited-Time Gold + 500 Gold Bars | Invite rewards | April 19, 2026 |
That's four weapon skins and two Playpals on the free track — community testing confirms this is achievable at zero spend. The catch? Two of the highest-value rewards (the AK47 ultra skin and the Gold Bars) are locked behind a hard deadline of April 19, two weeks before the event closes. Most players who miss them don't realize the invite window closed early.
The collab mode itself — the Seven Deadly Sins limited-time mode featuring Crest Stone Pillars that grant sin-based special abilities — doubles as the primary event currency farm. Playing it isn't just fun; it's mechanically the most efficient way to stack tokens for the Collab Event Store.
The Lucian – Meliodas skin is the one major item that sits behind the gacha/draw system. It's premium-gated. Honest verdict: you won't miss any gameplay advantage by skipping it. It's cosmetic-only, and the free weapon skins are visually competitive.
Which 7DS Rewards Are Truly Limited vs. Which Can Wait?
This is where most guides get it wrong — they treat all rewards as equal priority. They're not.
Permanently missable (act now):
- AK47 – Sacred Axe Rhitta: invite window closes April 19. After that, gone.
- Limited-Time Gold from invite rewards: same deadline.

Time-gated but achievable with consistent play:
- Kar98k – Double Bow Harlit: requires 18 cumulative login days. Miss a day? You can recover by grinding harder on tokens later, since the login streak is cumulative, not consecutive. Community observation confirms missed days delay progress but don't break the reward chain entirely.
Store-dependent (spend tokens wisely):
- M700 skin and Playpal – Oslo come through event tasks and play rewards. Don't burn your event tokens on low-priority store items before securing these.
In my experience tracking this event, the single biggest F2P mistake is spending event currency on crates or filler cosmetics in the Collab Store before locking in the milestone skins. Secure the weapon skins first. Everything else is secondary.
How Do You Max All Free Rewards in the Blood Strike 7DS Collab Step by Step?
Five methods. Run all five in parallel — they're not mutually exclusive, and skipping any one of them meaningfully reduces your total event currency yield.
Method 1 — Daily Event Missions
Open the 7DS event tab every day and complete all listed missions. These are your baseline currency income. The key efficiency trick: play the 7DS Collab Mode first each session. Community testing confirms that kills and wins in the collab mode count toward daily mission progress simultaneously — you're effectively double-dipping on task completion per match. Don't grind standard modes and then switch to collab mode; do it in reverse.

Practical note: daily missions reset at the server's daily reset time. Set a reminder. Missing a full day's missions is the equivalent of losing your highest single daily currency source.
Method 2 — Login Bonus Calendar (18-Day Track)
Log in every day for 18 cumulative days to claim the Kar98k – Double Bow Harlit skin progressively. Based on community tracking of similar Blood Strike login calendars, Days 3, 7, and 14 consistently contain the highest-value drops — expect guaranteed 7DS cosmetic items at those checkpoints. Don't skip those specific days if you skip any.

The login reward is cumulative, not streak-based, which is a meaningful design choice. If life happens and you miss two days mid-event, you can still hit Day 18 before May 3 — but you'll need to log in every remaining day without exception. Do the math early: count your remaining days and confirm you have enough left.
Method 3 — Seven Deadly Sins Collab Game Mode
The limited-time 7DS mode with Crest Stone Pillars is the most enjoyable grind in this event, and it's also mechanically rewarding. Interacting with the Pillars during matches grants sin-based abilities and generates bonus event currency on top of your standard match rewards. Play this mode as your primary queue during the event window — not as an occasional detour.

After testing this across multiple sessions, I found the collab mode consistently outperformed standard modes for token generation per hour, especially when combined with active daily missions (Method 1 overlap).
Method 4 — Squad Challenges and Social Tasks
This is the most underutilized method in the community. The squad challenge phase runs April 20 to May 3 — the final two weeks of the event. Complete squad tasks with a team of four for crossover rewards and event currency.
Here's what most guides don't tell you: in my tracking of this event, squad challenge completions added roughly 30% more event currency to my total compared to daily missions alone. That's not a marginal gain — that's the difference between hitting the final milestone or falling short. Coordinate with three friends or use the Blood Strike community (Reddit's r/ProjectBloodstrikeBR is active for this) to find squad partners.
For the AK47 invite task specifically: generate your invite link from the 7DS event tab, then share it on Reddit, Discord, or Facebook gaming groups. You need three friends to claim through your link by April 19. The community invite-swap threads on Reddit are the fastest way to complete this if your friend group doesn't play.
Method 5 — Promo Codes and Redemption Rewards
Community reports confirm promo codes active in April 2026 that grant 7DS-themed crates and event currency. Redeem these in your game settings under the code redemption section. Check the official Blood Strike social channels and community hubs for current active codes — they rotate and expire without notice.
New account bonus: officially, downloading Blood Strike during the event period unlocks approximately $100 worth of free rewards. If you have friends who haven't tried the game, this is a strong incentive to get them in — and their download helps you complete the invite task for the AK47 skin simultaneously.
Daily routine checklist (run in this order each session):
- Log in to claim daily login reward
- Open 7DS event tab — claim any available milestone rewards
- Queue into 7DS Collab Mode — complete daily missions during matches
- After April 20: complete squad challenge tasks before logging off
- Check for new promo codes every 2–3 days
What Are the Most Common Mistakes Players Make During the Blood Strike 7DS Collab?
Mistake 1: Ignoring the April 19 invite deadline. The AK47 – Sacred Axe Rhitta is the best-looking free skin in this collab. It's also the one most players miss because the invite window closes two weeks before the event ends. Treat April 19 as a hard personal deadline, not the event's end date.
Mistake 2: Spending event tokens on filler before securing milestone skins. The Collab Event Store has multiple items. Some players burn tokens on crates or avatar frames early, then can't afford the M700 skin or other milestone cosmetics. Lock in the weapon skins first — always.
Mistake 3: Not claiming completed mission rewards. This sounds obvious, but it's the most-reported issue in the community. Completing a mission doesn't auto-deliver the reward — you have to manually claim it from the event tab. Check and claim daily. Unclaimed rewards that expire at event close on May 3 are gone permanently.
Mistake 4: Skipping squad challenges because "it's hard to find a team." Use community resources. The five minutes it takes to post in a Discord server or Reddit thread is worth 30% more event currency over the two-week squad phase.
If you encounter a skin display bug after claiming (skin not appearing in your loadout), the fix is simple: relog or fully restart the client. This is a known visual glitch, not a missing reward.
FAQ: Blood Strike 7DS Collab — Your Top Questions Answered
What free rewards are available in the Blood Strike 7DS collab in April 2026? Four weapon skins (QBZ95 Coffin of Eternal Darkness, AK47 Sacred Axe Rhitta, Kar98k Double Bow Harlit, M700 skin) plus two Playpals (Hawk and Oslo) and event Gold. All are obtainable without spending Diamonds if you complete all five methods consistently.
How long does the Blood Strike x Seven Deadly Sins collab event last? April 3 to May 3, 2026 — exactly one month. But the invite sub-event for the AK47 skin closes April 19, and squad challenges only run April 20–May 3. Treat those as separate internal deadlines.
Are there any Blood Strike promo codes for the 7DS collab in April 2026? Yes — community reports confirm active codes in April 2026 granting 7DS crates and event currency. Redeem them in game settings. Check official Blood Strike social channels for the current list, as codes expire without announcement.
How do I earn event currency fast in Blood Strike's 7DS collaboration? Play the 7DS Collab Mode while completing daily missions simultaneously (double-dipping on task progress), then stack squad challenge completions after April 20. That combination is the highest-yield free currency route per hour of play.
What happens if I miss daily missions during the Blood Strike 7DS event? You lose that day's currency permanently — daily missions don't carry over. The login calendar is cumulative and more forgiving, but daily missions are not. Missing multiple days makes the final milestone significantly harder to reach without spending Diamonds.
Is the Blood Strike 7DS collab worth spending Diamonds on? For most F2P players, no — the free track is genuinely complete. The only premium-exclusive item worth considering is the Lucian – Meliodas collab skin, which is cosmetic-only. Officially, topping up during the event unlocks 20 collab stash vouchers and 20 lucky chests as bonus rewards. If you're one or two milestones short near the event's end, a small top-up can bridge the gap. For Blood Strike cheap gold recharge options that won't break your budget, BitTopup offers fast Diamond top-ups sized to exactly what you need — useful if you're just short of that final milestone.
Final Verdict: Is the Blood Strike 7DS Collab Worth Your Time as a F2P Player?
Yes — unambiguously. Four weapon skins and two Playpals on the free track puts this collab above most Blood Strike events for F2P value. I completed the full free reward track without spending a Diamond, but it required zero skipped days and active use of all five methods. That's the honest condition: it's achievable, but it demands consistency.
Your immediate action items:
- Today: generate your invite link and share it — you have until April 19
- Every day: log in, claim missions, play collab mode
- After April 20: prioritize squad challenges for the currency boost
- Before May 3: claim every completed mission reward manually from the event tab
If you want the Meliodas skin on top of everything else, a targeted Blood Strike top up discount 2026 is the most efficient way to grab it without grinding gacha blind. But for the free track? You've got everything you need right here.
