The idea of protect round is to defend against all damage heroes except poison heroes. Templar Assassin”s ability: Refraction defends against poison heroes, but it’s not castable on allies. It’s not a perfect ability. I originally had it to protect against mana loss also until you get attacked or something. But, It would not be good against Phantom Lancer and Magena except Phantom Lancer can counter the ability with Orb of Venom. So i took out the mana loss until i can remake the ability or put it somewhere else.
