@booboo That kind of begs the question, what is the purpose of a familiar? Are they just supposed to add a bit of RP flavor? Are they supposed to act as rather incompetent melee protection for a spell caster? Enhance his or her spell casting abilities?
In some prior version(s) of D&D, familiars had the ability to deliver touch spells cast by their master. An interesting mechanic, but it certainly put their pets in jeopardy. I'm not sure why this ability was added in the first place, or why it was removed in subsequent editions.
