Mighty Arms Graft, Battlefist, Wand Sheath, and Proficiency

[realbombchu]

Hey everyone. I'm about to rebuild a character I drafted before, and I have some questions. I just bought Faiths of Eberron, but it hasn't arrived yet.

1) A battlefist is just an accessory to a warforged's slam attack, right?
2) Does it require a proficiency feat?
3) Can you use a wand sheath at the same time?
4) What if you are a human with the Mighty Arms graft?
5) Does the Mighty Arms graft replace both arms?
6) Is there a penalty for fighting with a battlefist because of it's ogre-size?
Thanks!

1) Sort of it boosts slams and unarmed strike.

2) No, but you might need imp unarmed strike if use unarmed strikes. You already are prof with your slam.

3) As far as I know.

4) Mighty arms essentially let you treat your arms as warforged arms.

5) Generally yes does it make a difference for you?

6) No the ogre part is just flavor text to give you an idea that it is a big fist. It is designed to be used by medium sized warforged and possibly small warforged scouts.

Thanks for the help. It doesn't really matter that the graft replaces both arms, I was just curious and couldn't wait for the book.

Ah I understand. Sometimes it is cooler to have only one mechanical arm anyway (though you have to by the rules).
