It appears that mercenaries are ordinarily 0th level characters. Are the Elf and Dwarf mercenaries that can be hired (as opposed to Fastness and Vault followers, which are specifically mentioned to be lst level) 0th level too? Or are they considered to be lst level? Just a question that occurred to me while playing around with the domain rules.
Completely untrained human conscripts are very weak: HD 1/2, hp3, Attack Throw 11+, Save NM.
75% of human mercenaries are 0th level characters with some training: HD 1-1, hp4, Attack Throw 11+, Save Normal Man. 25% of mercenaries are veterans, 1st level fighters: HD 1, hp5, Attack Throw 10+, Damage By Weapon +1, Save F1.
Dwarven mercenaries are 1HD monsters, as per the stats in the Monsters section. Elven mercenaries are 1+1HD monsters, as per the stats in the Monsters section. They are effectively veterans and 1st level.
