GemSlasher is a fast-paced action roguelite where every attack is built from gems.

Combine Main Gems with Support Gems, merge duplicate gems to increase their star level, and create powerful builds capable of tearing through relentless waves of monsters.

BUILD YOUR OWN GEM COMBINATIONS

Each Main Gem determines how you attack, while Support Gems modify how that attack works.

Increase attack speed, boost damage, add projectiles, unleash repeated strikes, inflict bleeding, and discover combinations that can completely transform the way you fight.

Equip multiple Main Gems and combine powerful manually activated attacks with skills that trigger automatically.

MERGE, UPGRADE, AND ADAPT

Collect duplicate gems and merge them to increase their star level.

With every reward, shop visit, and upgrade choice, you can strengthen your current build—or take it in a completely different direction before the next battle.

Experiment with different gem combinations and discover new ways to build your character with each run.

SURVIVE ESCALATING WAVES

Fight through increasingly dangerous waves, using rewards and shops between battles to strengthen your build.

As the run progresses, enemies become more numerous and more dangerous, forcing you to continually refine your gem setup and make the most of every upgrade.

CREATE DEVASTATING BUILDS

Combine gems to create rapid melee attacks, projectile-heavy setups, bleeding-focused builds, repeated strikes, and other powerful synergies.

Experiment with different characters and gem combinations to find the playstyle that suits you best.
