Not sure if this has been mentioned here yet, but Eldritch Knight's (wizard one at least) Force's Point: Martial is behaving very wonky when casting a persistent aoe like acid fog. When you cast a spell that lingers like acid fog, it will trigger Force's Point: Martial, however when it tries to apply a second stack of it, it can sometimes remove all stacks instead or just remove stacks applied by the lingering aoe, or just not apply additional stacks at all. The way to reproduce this would be to set the lingering aoe between you and a group of enemies, once it is in place, pull the enemies through the aoe, and then perhaps drag them out of it and back in. if the enemies remain in the aoe or it is cast onto the mob, it may only apply one stack of Force's Point: Martial if at all. Overall the interaction between lingering aoes and Force's Point: Martial does not seem wai, and I imagine it is probably also the same with the arcane warrior destiny feat since they seem like they would be coded the same way.
