Kai’Sa

Play as the Daughter of the Void in Risk of Rain 2. Mark enemies with plasma, unleash missiles and reposition with a directional dash.

The mod includes 16 appearances, skin-specific animations and projectile visuals, English voice lines, original Bullet Angel sound effects, two secondary skills and two passive choices. Menus and ability descriptions support English and Russian automatically through the game's language setting. Other languages use English.

Abilities

Slot	Ability	Effect
Primary	Living Weapon	A guided plasma shot that applies a Plasma mark. A purple marker identifies the selected target.
Secondary	Icathian Rain	Six missiles split among visible enemies within 35 m; ten missiles while evolved. Deal 25% more damage if only one visible enemy is in range. Each volley applies one Plasma mark per target.
Secondary alternative	Plasma Fission	A large shot explodes in a 5 m radius for 280% damage and two Plasma marks. Four shards hit enemies behind the impact for 80% damage and one mark; six shards while evolved.
Utility	Supercharge	Gain movement speed, followed by attack speed. Primary attacks remain available during the boost.
Special	Killer Instinct	Dash 28 m in your movement direction and gain temporary barrier. With no movement input, dash towards your aim, including upwards. Walls stop the dash.

Five Plasma marks detonate on the enemy. A five-petal marker shows the current stacks.

Choose your passive

Second Skin: kills charge evolution: 4% for a normal enemy, 8% for an elite and 20% for a boss. At full charge, press V to evolve for 30 seconds. Evolution strengthens the abilities and adds a purple tint at the edges of the screen.

Void Hunger: the second skin demands sacrifice. Each offering feeds its hunger and makes Kai’Sa stronger. This passive replaces evolution while keeping the five Plasma marks. Each kill heals 5% of maximum health and grants 1% attack speed for the rest of the run. Lose 0.5% of maximum health per second, plus another 0.5 percentage points per second for every 100 kills. This drain stops at 1 HP. Natural health regeneration is disabled. The model glows brighter with every 100 kills.

Install with r2modman or the Thunderstore Mod Manager. Required dependencies install automatically.

For manual installation, install the dependencies listed in manifest.json, then copy BepInEx/plugins/KaisaPrototype into your profile's BepInEx/plugins folder. Replace an older copy of this mod instead of keeping a second DLL. Keep the asset bundles, sound banks and Icons folder beside the DLL.

For multiplayer, every player needs the same game and mod versions. Use the same gameplay configuration on all computers. This package is version 0.2.15.

Default controls: M1 primary, M2 secondary, Shift utility, R special and V evolution with Second Skin. Normal skill keys follow your game settings. The evolution key, voice options and gameplay values can be adjusted in BepInEx/config/ykyshka.kaisa.prototype.cfg; ability values above describe the defaults.
