Tier 3 Wolvers (both normal and alpha) are broken. They have 2 bugs that make them very hard to play with.
Bug 1: while being frozen they execute "dodge" move freely, unlike any other monster capable of using that move. Which defeats purpose of freezing: they move, they rotate.
Bug 2: regardless of being frozen, they execute their dodge move in the middle of attack. Basically they teleport behind you the moment they're biting, making this attack impossible to dodge. This mostly happens when I'm shooting my gun (in any direction).
Why I think these 2 "features" are bugs:
a) fiends, gremlins, ghosts, zombies can't do their dodge or rush attacks while being frozen. No monster capable of moving at increased speed can use that special move while being frozen, they're stuck in place. Wolvers can ignore their "frozen" condition and move freely, including being able to aim at different directions.
b) teleport-attack has no warning (unlike jellies who mark the ground before the spikes appear), thus making it impossible to predict and dodge. On top of that it happens in the middle of another action (attack), which no other monster can do (no other monster can combine two attacks together - gremlins don't swing and heal at the same time, and they don't go dodging while in the middle of a swing, same as robots who won't put their shield up while swinging their sword).
I believe the problem lies in the ability of wolvers to execute their "dodge" move, regardless of its "cooldown" period (check is missing? cooldown period missing a "0"?), or ability of wolvers to execute their dodge move whenever someone's attacking (as if there is another check missing - weather they're allowed to execute this move under current conditions - did not execute it before, are not in the middle of another action).
