As mentioned above, the only difference is that corruption gets past Possession Immunity. To stop it you need Immune to Control, Gravedigger, or Abomination
Hehe no, not at all. There used to be several different "exclusive possessions." They were possession abilities designed to bypass the immune to possession trait. But eventually, SP consolidated them all into the 'corruption' effect.
Thesot,I also believe possesion has a chance to make the attacker attack one of their teammates,but corruption says they will attack,if I am wrong could you please tell me
