Grindylows as monster mercenaries do not gain the damage resistance they should when burrow is used.

Can we just have the move removed from them as mercs? If you set them to ai controlled they wasted their first turn burrowing

[Shujin]

Or! You just don't use them?

[Noxid]

But they are cute!

This isn't a discussion forum, if you don't have relevant information to the bug report then don't post.

They have significantly reduced damage reduction while mercenaries, this is intentional.
