It's that time again. As one user pointed out, since E15's fields have been implemented, I can finally start announcing some of them. But one at a time. Small bites. Chew before you swallow.
Or better yet with this field, try not to swallow anything at all, because it'll kill you from the inside-out.
I've basically already confirmed this one, so we may as well start with it, hm? The Murkwater Surface is a hybrid between the Water Surface and some of the other poison fields. Created by using Sludge Wave on the existing water fields, Murkwater makes a pretty miserable time for all but the select few Pokemon who benefit from both sides of it.
But, perhaps it could be useful against a certain trainer, if at some cost.
E15 is chugging along, but we're obviously not there yet. Don't worry though, I'll do my best to cut through the rest of it... so to speak.
