I have on BT long ago, well not katayanna anyway.
Though I did not like being on the receiving end. We did beat them back But there were just too many of them unlike Dwilight where there are a relatively few Zuma units/characters running around.
Yeah, if Fang Fang was on BT Thalmarkin would already be cleaning Daimon-guts out from between the treads of their boots, and they're not a real big realm.
