Soldier's Syringe (Risk of Rain 2)

not to be confused with the first games version, the Soldier's Syringe.

Soldier's Syringe is a returning item in Risk of Rain 2. Passively increasing attack speed with all abilities, it remains largely unchanged from the first game. However, this version doesn't cap out after 13 stacks. Being one of the few common items that unconditionally increase the users DPS, they are highly valuable for every class and one of the best common items in the game.

Visually, the Syringe is shown on the players right thigh or knee, sticking out and flailing as they run.
