the question is the same, how it could work? if it's a set of triggers, they must be very abstract to be apllied in combat in different locations, circumstances, etc. But if they are abstact, we somehow need to be sure that this particular trigger will fit my combat plan, or else we'll never use this action again because of its unreliability
The way I see it, you’d mark an area on the floor and select an offensive action. The next enemy to enter that area would instantly be the target of whatever attack or spell you chose.
