(sburb rpg) yeah it's a bit more difficult in the early game ironically, with all the game constructs and whatnot. For classpects, I was thinking of just giving them a list of verbs associated with their class, and a list of nouns associated with their aspect and saying "if you can combine those to do something, you can probably do it." like you said you were seer of doom. just off the top of my head, if someone lands a killing blow on you you could say "I say that beforehand", and avoid it.
Definitely an interesting system, if you can get anything other than Critical Misses of course. :^) It could be a really cool concept though and I hope it develops nicely!
