|Drop a Warbanner on level up or starting the Teleporter event. Grants allies attack and movement speed.|
|On level up or starting the Teleporter event, drop a banner that strengthens all allies within 16m (+8m per stack). Raise attack and movement speed by 30%.|
The Warbanner is a returning item in Risk of Rain 2. Upon leveling up, or when the respective Teleporter Event's boss appears, the player drops a banner onto the ground which produces a yellow bubble that increases attack speed and movement speed by 30% while inside it's radius. In multiplayer, upon starting the Teleporter Event, ALL players with a banner will drop one at their feet.
- While the radius scales linearly, the area of a circle as the radius increases scales exponentially (Area = π * r ²). This means in multiplayer it is stronger to stack this item on one player rather than across several players. 2 players with 1 Warbanner each would cover 1,608.5 square meters, while 1 player with 2 Warbanners would cover 1809.6 square meters.
The position of the banner is always placed at the player's feet, and is NOT affected by gravity. This includes teleport event activation, so it is better to be located near the teleporter when the boss spawns to maximise its benefit.
