Bergmite, the Ice Chunk Pokemon, is a pure Ice type Pokemon. It can be found in the Frost Cavern near Dendemille Town. It can be found at the lowest level of 39 and highest level of 40. It evolves at level 37, so all Bergmite you find here will be ready to evolve. Once it does, it will become Avalugg, the Iceberg Pokemon. Ice Pokemon are useful especially against Drasna. But Frost Cavern is full of other Ice Pokemon. Why get a Bergmite?
I don’t feel anything unique about this Pokemon. I’m not saying you shouldn’t get one, but you should consider getting other Pokemon in the Frost Cavern. But, this may not be necessary if you already have a team set up for defeating Drasna. Ice Pokemon would have been more useful earlier in the game against Ramos, but the only one available then was Amaura. Even then, it’s not the best Pokemon to use there since Amaura is a Rock type Pokemon, which are weak to Grass type moves. If you plan on getting an Ice Pokemon in the Frost Cavern (or Route 17, there are Ice Pokemon available there as well), here’s a list of ones (besides Bergmite) you can get:
If you don’t like Bergmite, there are a total of eight Pokemon you can get around Dendemille Town.
Did you get an Ice type Pokemon on your adventure through Kalos? If so, what did you get?
