From publisher blurb:
Get more familiar with familiars . . . .
A familiar is an integral part of a wizard's or a sorcerer's capabilities. They grant numerous powers and abilities that afford the arcane spellcaster significant advantages. Considering the potential importance familiars can have in a campaign, the rules on familiars in the Player's Handbook and the DMG are surprisingly sparse, fractured, even incomplete. Betabunny's Guide to Familiars provides a thorough coverage of the subject of familiars. In its 39 pages, Betabunny's Guide to Familiars includes:
A well-organized and comprehensive set of rules for using familiars in your campaign
10 rules supplements and clarifications that fill in the gaps in the Player's Handbook and the DMG
Variant rules and roleplaying tips that will give you a better framework for using familiars in your game
9 new feats, 13 new spells and 2 new special abilities
20 high-quality illustrations, diagrams and tables
Stats and a description for the white-faced capuchin monkey along with a template showing how to convert a creature into a familiar
Many other elements designed to entertain, educate, and give you greater insight into how to use familiars in your campaigns.
