What Makes This Blood Strike × The Seven Deadly Sins Collaboration Worth Watching?

It is not just about crossover skins, but three content tracks launching together

This collaboration is built around three main parts. The first is a set of free event mission lines. The second is the limited-time Featured Seven Deadly Sins Treasure and Seven Deadly Sins Lucky Spin. The third is the exclusive crossover mode Sin Mark Duel. In this mode, players can interact with Crest Stone Pillars on the map to gain Crest Abilities, which provide special combat enhancements during the match.

For most players, the free rewards are absolutely worth claiming

The free side of this collaboration is far from filler content. During the event period, players can collect crossover rewards through login tasks, friend invites, Gallery collection missions, friend bargain support, and team-up objectives. These rewards include weapon skins, avatars, Playpal cosmetics, avatar frames, and limited crossover titles. In other words, as long as you stay active throughout the event, you can build a solid set of themed rewards without spending heavily.

Blood Strike × The Seven Deadly Sins Draw Rewards

If you care more about headline crossover cosmetics, then the real focus is not the free event tracks, but the limited-time draw pools.

Reward	Type	How to Get It	Free?	Priority	Best For
Lucian - Meliodas (Demon)	Character Skin	Featured Seven Deadly Sins Treasure	No	Very High	Players chasing the main crossover showcase skin
Emma - Elizabeth (Goddess)	Character Skin	Featured Seven Deadly Sins Treasure	No	Very High	Players who like high-visibility female character skins
M4A1 - Demon	Weapon Skin	Featured Seven Deadly Sins Treasure	No	High	Players who use M4A1 regularly

Lucian - Meliodas	Character Skin	Seven Deadly Sins Lucky Spin	No	High	Players with a mid-range event budget
Playpal - Wild	Playpal	Seven Deadly Sins Lucky Spin	No	Medium	Players trying to complete the crossover set

Official event information confirms that M4A1 - Demon, Galil - Elizabeth, Lucian - Meliodas (Demon), and Emma - Elizabeth (Goddess) are part of the Featured Seven Deadly Sins Treasure. Meanwhile, Lucian - Meliodas and Playpal - Wild are available in the Seven Deadly Sins Lucky Spin. So if you are already thinking about stocking up on Blood Strike Gold for this crossover, it is smarter to decide first whether you care more about character presentation or about weapon skins you will actually see in regular matches.

Character-focused players and gameplay-focused players should prioritize differently

If you are mainly a character collector, then Lucian - Meliodas (Demon) and Emma - Elizabeth (Goddess) are usually the top priorities. If you care more about what you will notice every day in combat, then M4A1 - Demon and Galil - Elizabeth may feel more worthwhile in the long run.

Blood Strike × The Seven Deadly Sins Event Schedule

This is the most useful table to save if you want a clean event roadmap and do not want to miss any mission windows.

Time	Event Content	Possible Rewards	Importance	Recommendation
4/3–5/3	Cumulative Login	Kar98k - Double Bow Harlit, Avatar - Hawk, Crossover Avatar Frame	High	Log in daily and do not break the streak
4/3–5/3	Full Collaboration Period	Multiple reward tracks active at the same time	Very High	Stay active throughout the full event
Starting 4/3	Featured Seven Deadly Sins Treasure	M4A1 - Demon, Galil - Elizabeth, Lucian - Meliodas (Demon), Emma - Elizabeth (Goddess)	Very High	Main priority for players chasing core premium skins

During the collaboration	Sin Mark Duel Mode	Exclusive crossover gameplay experience	High	Worth trying if you want the full crossover experience

The easiest mistake in this collaboration is not failing a draw, but forgetting parts of the free mission schedule. The reason is that not everything opens on day one. Several reward lines unlock in phases, so if you want to stay efficient, it is much smarter to follow a clear timeline and keep track of each event window.

Blood Strike × The Seven Deadly Sins Collaboration Summary

For free-to-play and light-spending players: clear the free tracks first, then decide whether to add Gold

If your goal is to join the collaboration without wasting resources, the plan is simple: claim as many free rewards as possible first, then decide whether you truly still want a specific crossover character skin or weapon skin afterward.

For players chasing the main crossover cosmetics: set your budget early

If you already know that you want Meliodas- or Elizabeth-themed premium cosmetics, the most important thing is not to make a last-minute decision. Set your budget early. Since the collaboration ends on May 3, waiting until the second half of the event usually means trying to finish mission tracks and premium pulls at the same time, which makes resource planning much messier.

Overall, this Blood Strike × The Seven Deadly Sins crossover is one of the more complete collaboration events the game has released so far. The free rewards have real value, the premium draw pools have strong visual appeal, and the event even includes its own dedicated gameplay mode. For most players, the safest route is to secure the free rewards first, then decide based on your favorite weapons and character preferences whether it makes sense to do a cheap Blood Strike top up and invest only in the crossover content you actually want.
