Never player Heroquest, so most of this is crazy wild stuff to me. Though I suspect it would be crazy and wild even if I had played HQ. Good on you for letting the players have their crazy shot.
I will say that your Trickster seems to play their character wonderfully. Great job. Our RQ:G group has a Eurmali, first time in ages we've had one, and I gotta say, roleplaying wise, IMO, he's the Worst Trickster Ever. But, concerning how another player runs their PC, my opinion is really worth nothing.
