Hmm - well, I guess I just want to make some events for thieves to make them useful

Maybe there are variables to grab those skill numbers?
For example, we could have:
1. Random trap events (imagine a level of random wandering kobolds, who like to set up traps and such to kill wandering PCs).
2. Treasure chest events (after a battle with monsters)
Not sure what to do with hiding in shadows/move silently/climb walls skills - since they are useless if the rest of the party is with the thief. For the latter, I can only think of treasure that is left in a high nook or something - then you can try to climb to get it, I guess.
