I'm in the middle of converting several 3.5 Paizo modules into PFRPG (the Darkmoon Vale ones), and I wanted to bring a few of the NPC kobolds up a notch. I was thinking that Grugakrug would make for a fine cavalier, and I'm looking for help to make him an interesting fight that the players will talk about for sessions to come. Not quite Merlokrep awesome, but still tough and interesting.
So far, my idea is to put him on a cave raptor or lizard special mount and replace the Dark Talon Hunters with goons on lesser versions of his mount. Any ideas?
