Thank you for playing!
The ghosts had to have a lot of health to encourage player to use the marks, becouse you cant just just kill them with the regular projectiles. Players can use the green mark to combo the enemies and kill them with one mark cast. But the thing is, player has to constantly feel they are in danger, so instead of facing the wraith they better escape and regroup, that's why you are faster.
Yeah, I should probably add a some kind of a tip...
