unless you're asking for Moggle mog Ex, which I haven't tried (due to some titan still up), you may talk about the gladiator's ability, which targets the tank having him and the 2 nearest person when the cast begins. afaik, the warrior's ability just does a circle AoE around him.

Either way, the only way to make the warrior and the gladiator stop their abilities is either to pacify them (not sure if it works well. It does wonder against Diabolos on a side note) or to kill them, which is the safest imo ^^
