I’ve been contemplating a battle plan.
I know they only last minutes for the sustained.
If I were obnoxious I would make heal spells in preparations as clown noses and stat boosts in neck ruffles, and improved reflexes in poofy wigs. Just to be clear, I am obnoxious.
But I wouldn’t want to blow them all. I’d try to stay in a place to get maximum LOS of my group. That way, if I’m not shooting with my own buffs helping, I’ll be able to activate their buffs or heals and call out leadership actions as needed. For combat I’ll be shooting(haven’t decided what), counterspelling, and commanding my summons.
