ToME: the Tales of Maj'Eyal

Alright, got a weird one for you. Whilst playing as a sawbutcher, got the skirmisher class unlock. Despite no ranged weapon, and I haven't touched block all game. Much less in a way to earn this unlock. Posting the (unfortunately large logfile), hopefully someone can figure out how this actually happened.

Earned the unlock after using bloodstream.

It can actually be unlocked by enemies meeting the unlock condition.
