This guide covers how to kill Alchemical Hydra in Old School RuneScape (OSRS): the best gear setups, prayers, inventory and locations. This OSRS boss guide works for ironman and regular accounts, and covers whether a cannon or safespot can be used. It doubles as a money making guide, and will help both low and high level players get their kills.
