Slime Slayer is an action-packed roguelite where you exterminate EVERY LAST SLIME! Craft unique character builds in every run with compounding modifier runes.
7 Base Abilities, each with 5 Elemental Variants Create your spells with a base and element! Fireball? LightningBall? Ice Meteor? Void Meteor? Build your spell how you want it!
Pick Your Element: Every spell can be evolved with every element, and every element is mechanically distinct! Learn the strengths and weaknesses of each element and how to best combo them to craft a slime-killing machine!
Build Your Spells: All modifier runes can apply to all skills, and each rune compounds in a way where sequence matters. Learning how different runes build off of each other allows you to create unique and incredibly deadly combinations to slay even the most powerful slimes!
11 Unique slimes, and 7 different bosses Traverse between the Forest, Desert, Crystal Caves, Floating Isles, Arctic, Volcano, and Void Zones to encounter unique slimes and bosses! Each Combat room can RuneCharged and HeartCharged, empowering all slimes inside. The more powerful the enemies in a room, the greater the reward!
Relics: Take your build to the next level with distinct Relics! Relics are non-stacking unique global modifiers that empower your builds, giving you new paths to power with every run!
Multiple Gameplay Difficulties: Up for the challenge? Test your skills in making the strongest build you can in Hard mode or Hell mode! Then test your build's power in the Gauntlet!
