First off, sorry for today's late post. No excuse for it really, I just messed up on the timing for it.
Second: A key antagonist can be a great way to get your players involved in a plot line emotionally. The way it works is you present an antagonist who is basically a recurring villain always making things hell for the players.
For today's discussion I wanted to ask who is doing this right now, who has done it with good results in the past, and how you did it?
I'm also interested in folks sharing stories of dismal failures. One of the most common ways this happens is when a PC with a lucky crit and a couple lucky die rolls ends up killing this antagonist.
So, who is doing it, and how is it going?
