@Salfaro if u remember one of the litch abilities was that he can't be seen by lower level monsters but in kana's case he wanted to show her the lich it s different since they re all lower level than the lich they can't see him
They use projectiles so i thought it was a good idea to fight on open land(there is no way to hide from projectile in an open land and they can snipe all of u like ducks even with a bow )
With wt strategy or logic
No wonder they re about to go extinct x)
