The Warbanner is a returning item in Risk of Rain 2. Upon leveling up, the player drops a banner onto the ground which produces a yellow bubble that increases attack speed and movement speed by 30% while inside. This item can be useful when stacked excessively to the point where the radius spans the entire level or if the player is lucky enough to level up near the teleporter for some bonus damage, however the bonus it provides is overshadowed by other attack-boosting items.
