What does the boost with the 4 stars do? You have the sword for attack damage, Shield. Health. Boots. Stars..... ?
It briefly unlocks all your feats.
it will not reset your feats cooldowns if they are already on cooldown from a previous "stars buff" though. it's only really useful if you can get it early in the match.
Ah yes so it does Don't know how I didnt notice this when activating it xD
