The runt attacks only with magic, so using Protect from Magic or Deflect Magic will reduce the severity of its attacks. However, if players are next to a runt, the runt can infest the player, dealing fast hits of 72 to 144 life points. Infestation stops if the player moves away from the runt or kills it. Infestation can be temporarily prevented by sprinkling neem oil on the runt. Due to their small size, they are usually a nuisance to deal with when safespotting. It would be best to kill them if mass killing ganodermic beasts. Ganodermic runts have very similar drops to grifolaroos.
