Pick a League of Legends champion and survive Minecraft with their kit.
From your own League of Legends install (nothing of League is shipped; the mod reads it while you play):
the champions' 3D models, textures and animations: in third person you are Ahri, Garen or Ashe, idling, running, attacking and casting Q/W/E/R just like in League
the champions' portraits, names and titles in a League-style champion select, with their real lock-in voice line
every ability's icon, name and description
League's own cooldowns and mana costs, rank by rank
Champions in this version
Ahri: Orb of Deception flies out and back, Fox-Fire, Charm pulls mobs to you, Spirit Rush dashes three times
Garen: Decisive Strike, Courage, a spinning Judgment, and Demacian Justice from the sky
Ashe: frost slows on every hit, Ranger's Focus, a Volley of arrows, Hawkshot reveals mobs, Enchanted Crystal Arrow stuns
How it plays
Survival-friendly: abilities use mana and cooldowns, Garen has none (like in League)
Your champion level is your Minecraft XP level + 1 (up to 18): abilities rank up and hit harder, R unlocks at level 6
The bottom-row keys Z / X / C / V (Y / X / C / V on German keyboards) cast Q / W / E / R (rebindable), K or /champion opens champion select again
Single player
First start: open or create a singleplayer world and champion select opens by itself. Press F5 to see yourself as your champion.
