About This Game

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

Combine Active Gems with Support Gems, merge duplicates to increase their star level, and create powerful skill combinations capable of cutting through relentless waves of monsters.

BUILD YOUR OWN GEM COMBINATIONS

Every Active Gem defines how you attack, while Support Gems change how that skill behaves.

Increase attack speed, amplify damage, add projectiles, trigger repeated attacks, inflict bleeding, and discover combinations that completely transform your combat style.

Equip multiple skill sets and balance powerful manual attacks with automatically activated skills.

MERGE, UPGRADE, AND ADAPT

Collect additional copies of the same gem and merge them to raise their star level.

Every reward, shop visit, and upgrade choice gives you another chance to improve your current build—or change direction before the next battle.

No two runs need to develop the same way.

SURVIVE ESCALATING WAVES

Fight through a sequence of combat, reward, shop, and boss waves.

Enemies become more numerous and dangerous as the run progresses, forcing you to constantly 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 builds, repeated strikes, and other powerful synergies.

Experiment with different characters and gem configurations to find a playstyle that fits you.
