@pathfinder Does Stay down proccing on an enemy standing up prevent Reactive Strike of another character from working on that same enemy? Does Topple Foe from Marshal archetype attempt to Trip an enemy before or after the Reactive strike if the trigger was a reactive strike for re-prone pseudo-Stay Down purposes?
Mhm the reactions are all triggered, would be insane when someone could interrupt the triggering action so that other reactions are then wasted.
@DmMacniel What about the second one. Does Topple Foe re-prone an enemy hit with Reactive Strike since Reactive strike is triggered by standing up and Topple foe is triggered by being hit?
You only have one reaction per turn.
So if an ally (which does excludes you) Reactive Strikes a prone enemy that tries to Stand (which is an action with the Move trait) and succeeds, you can then react to that successful strike to Topple Foe to Trip them thus causing them to get the prone condition again.
So yeah in a duo this would be possible, alone not.
