Bison Steak

Formerly known as 'Fresh Meat', Bison Steak is a new item in Risk of Rain 2.

The item grants the player a flat +25 maximum hp (+25hp per stack).

Trivia
Prior to the Anniversary Update, this item was known as "Fresh Meat," and instead of increasing maximum health, it increased base health regeneration by +2 hp/s for 3s (+3s per stack) after killing an enemy.

May be a reference to Team Fortress Two's "Buffalo Steak Sandvich"
