I can't get metal king slime Grotto maps yet. They're at least around level 64-68 or so. And I need to train a few more levels before I have a chance of getting one. And even then it would have to be water or MAYBE a volcano type.

So I guess I should stick with Baramos Lvl 2 because he gives me more exp then the other grotto bosses and its just him.
