Thanks for playing! You should be able to determine their health values relatively quickly by how many hits it takes to kill them. The basic green goblins don't have any Crit Chance, but the stronger ones do ;) I believe they also have higher Accuracy. Good luck killing the boss!
Yeah that's correct. I don't remember the exact value of the red goblin but somewhere around there. Crit Chance should be the same against all goblins, they don't have any defense/reduction against that.
