ah well i think so, well heres what im currently doing ill explain.
i have a npc who im using for gossip and when i talk to him and click the gossip menu option thingy, he summons a creature and activates an object, and thats all working just fine, and what i want is when that creature that he summoned dies like on that creatures death event i want the gossip npc to like update or go to next phase so that when i go talk to him again he will summon the next creature, so basically what im after is when a certain event happens on 1 npc i want this other event to happen on this other npc if that makes sense, so its basically going to work like the instance trial of the crusader/champion works where u talk to the announce and the events happen and the boss spawns if you get what i mean.
hope it wasn't confusing for you.
