From publisher blurb:
Bonus Underlings!Underlings, as it turns out, are very popular. Every warlord, necromancer, and petty tyrant could use a few bootlicks to take care of the chores. After all, planning the downfall of the civilized world is tiring work, and who has the time to do the dishes after all that cackling.
This bonus supplement to Rule Zero: Underlings is my way of saying thanks for supporting Minotaur Games. The rules presented here require the original PDF, but for those of you who have not yet checked it out, this supplement should give you a taste of what you’re missing. In total, this PDF contains:
3 New Feats related to Underlings
8 New Spells, allowing you to summon underlings of a variety of CRs
7 New Underling Race types, including elementals and lycanthropes
2 New Underling Universal Monster rules
Rule Zero: Underling Bonus requires the original PDF Rule Zero: Underlings to be fully utilized. It does not contain the complete underling rule system!
