Cool, I have changed the name in that place too :)
Just to summarise the familiar rules, since I can't find them on the compenduum! You seem to know them by the familiar description, but wanted to state them here anyway so you know what I know!
quote:
A familiar cannot attack, flank or manipulate objects (unless otherwise specified, ie Rat or Disembodied hand.)
It shares your defences and skill. It has 1hp and acts like a minion. It is not a target for any of your attacks (unless you want to). If it dies, it takes until a short or extended rest to recall it, with no penalty for it dying. It has two benefits, a constant and an active, and two modes, Passive and Active. While in passive, you gain the Constant Benefit and the familar shares your space, it cannot be attacked while in passive mode. You can use a minor action to switch the familiar to active mode, where it gains both the constant and active benefits. In active mode, it occupies the space of a tiny creature and you spend your actions to give it actions. So you spend a move action to move it up to it's speed, or a standard action to use a certain skill. The familiar cannot move more than 20 squares away from you, unless it is a benefit (ie Cats have no range limit). A familiar cannot speak (except parrots and ravens) but can communicate with you in "gibberish" that only you and the familiar can understand.
so the homunculuus can be in your pack Meri until you chuck it out :)
And yes, you can try to teach it to be your assistant,
Meri, this means your arcana skill should be +2 greater to be +11 right now.
