The same power in the 3.5 SRD says this:Deset Gled said:The Graft Weapon psionic power from the 3.0 Psionic Handbook had some rules for only having one usable arm (the power grafted a weapon into one of your hands, making the hand unusable).
SRD said:While your hand is grafted to a weapon, you lose the use of that hand and take a -2 penalty on all skill checks requiring the use of hands.[/srd]
It's probably not as hefty a penalty as if it were real life, but there's a lot in D&D that's not the same as in real life.
Aaron L said:6 points of Str and Dex damage. Ability damage is, I believe, the best way to represent things such as missing limbs, broken bones, and the like. I think its even stated to use it that way, but dont quote me on that, I cant rememeber any sources.
