I've tried this post three times, so lets see if it works this time . . .
Another thought for an action in this fight or later: you can "hold an action." The idea is that you say, "I want to do this specific thing, but I'm going to wait until this other thing happens." For example, you could ready an attack (or two if you get them)but not attack at you rnormal initiative. Instead you wait until an imp reappears and then attack. the reappearance of an imp is the stated trigger. Doing this allows you to time your attack with other events and react to things tht would normally happen after your turn in the initiative sequence. (Say, you go first and there is no imp to attack, but later in the round the imp reappears.) The downside is that if your trigger never happens (For example, an imp reappearing was the trigger an no imp reappears) then you have wasted your turn and do nothing.
Actually, this is a 5E rule. Not sure how it plays here..
I allow "hold action" in a round to go last if a person's initiative comes up and they have not been attacked or interfered with up to that point. Also like Nomad said above if your trigger does not happen you'll have wasted your turn for that round and that could change the course of a combat depending on that combat rounds results.
Also again my apologies got tied up in Real Life and was again unable to post. I promise soon.
Well, that really stunk. I had that litttle bugger right where I wanted him.
So, where does the suggestion leave Lothor? Can he do anything now? Look for imps? Attack them if they appear? Fight rats? Any limits? Does he need to just stand there and wait for the imp to reappear?
