Class FeaturesWeapon and Armor Proficency: A 0th-level character is proficient with one simple weapon. He is not proficient with any other weapons, nor is he proficient with any type of armor or shield.
1st-level: A 0th-level character starts with -500 xp. When they reach 0 xp, they may select a class. They gain hp equal to the difference between d4, and their new hit die, essentially losing the old in place of the new.
This is meant to be a sort of equivalent to the 0th-level character rules in DCC, as well as an alternative to the commoner class. It's meant to be used with background rules like the ones in Tome of Secrets, or some equivalent, so that a 0th-level character will in fact have a small number of class skills.
