Eidolon evolution idea for a Rogue / Summoner multiclass.

[Garricklar]

Okay, so I've been toying with the idea of having a very talky, charmy rogue, but with a kickass eidolon that's had an invisibility spell of some form cast on it.

I was thinking of house ruling an evolution that allows the eidolon to share abilities/class features as well as spells, so it can make use of sneak attack. Would people think that this is A: A good idea and B: worthy of a 2 or 3 point evolution?

Also, side note, can anyone direct me to any house rules or layouts for Centaurs as playable races? The bestiary book confused me. I had the crazy idea for a Centaur Cavalier with itself as its own mount.

Getting full sneak attack with an eidolon is probably 4 points or higher.

I wouldn't allow it, since you could have a large, pouncing eidolon with 5 attacks all doing sneak attack.

What if it was only on the first attack say?

That's a little weird, but not so bad. Then it'd probably be 3 or 4 points. I retract my previous statement that full sneak would be 4 points, and it would definitely be more than that. 6 might be OK, but probably not.

Energy Attacks is 2 points, and that's just +1d6 resistable damage on all attacks.

So sneak attack, eventually getting to +8d6 unresistable (but DR effected) damage (an average of +28 damage) is probably 4 points minimum. Honestly, with just the first attack, that's still pretty good, but I'm not sure if it'd be 3 or 4 points.

Well, it was just a passing thought. I'm still toying with the idea, but now my character idea has progressed more along the lines of the classic sneaky stabby rogue with his own personal, portable meatshield... I think this might work better in honesty. Thanks for the input though, much appreciated!
