  • Northern Turtle Legion Commander can summon a random player to it sometimes, with a chance of stunning them.
  • Northern Turtle Legion Commander takes heavily reduced damage. Poisons are more effective against it.
  • Legion Turtle Eggs explode and poison all entities in range upon being killed, as well as spawning Young Northern Turtle Legionaries. The poison cannot be covered by Detox.
  • Northern Turtle Legion Commander will change aggro randomly when an egg is killed. This is shown in General chat with the message "[player name], you will pay for this!!!".
    • It will relentlessly go after the player it targets in General chat unless another egg is killed.
    • Use this opportunity to lure Northern Turtle Legion Commander to one of the eggs and kill the egg. Do not stay on top of them; just make sure it goes past each egg.
