Have to apologize. Didnt notice the one charge in question was used up in an earlier fight.
So if im not wrong here again this Thread has no meaning anymore.
But it would have been nice to make the extra Monk attack and then use up another charge from cleric to make one other Action not related to hit the enemy, f.e. use charge to throw something somewhere etc.
Might be i restart Game because my idea of War Domain Multiclass into Monk for this kind of having more options is not really working out when onle taking one level of Cleric then directly going int Monk at Levelup.
