Dual classing

Tut, no, your advancement as a druid is not slowed at all, far as I can tell in the rules. You just can't do anything druidic until you've made it to 2nd level, then you're a 2nd level druid with 1st level bushi skills.

Not sure druids can even use bows though. Maybe slings or staff-slings. Seems silly, I guess a bow would be alright. Bows do 1d6 damage, not 1d8.
