What Damage would a 2H power hammer do?

A hammer does damage 1d10+1 I.

A great weapon does 2d10 R Pen 2

Sword: 1d10 R

Power Sword: 1d10 + 5 E Pen 6

Now:

I would say: 2H Hammer: 2d10 I

Power Hammer: 1d10+6 E

2H Power Hammer 2d10 + 5 E

I know, that would be too easy and too overpowerd... but what wold you take?

I forgot:

2H Hammer: 2d10 I Pen 2

Power Hammer: 1d10+6 E Pen 6

2H Power Hammer 2d10 + 5 E Pen 6

And what cost/aviability would you suggest?

Btw. sorry for the second Post... i didn't found the "Edit" -Button... Now I got it

Have you thought about simply copying the stats of the power fist? After all, it's generally considered to be the "heaviest" manportable power weapon.

That's an Idea! Thanks...

The other thing I thought about was:

2H Shocking Hammer, Damage 2d10 I, Pen 2, Unbalanced, Shocking, Aviability Rare, Cost 1300

That would't be THAT imba^^
