Silverback Mapboss

The Silverback Ape boss (from the jungle in act 3) engages before you even see him opening an arena - he engages you right away opening an arena that you then need to enter.
Upon entering the arena you get oneshot before being fully loaded in.
Fix the engage behaviour for the player to engage the boss not vice versa.

I didnt clarify this properly but i am talking about maps specifically
