It doesn't matter whether or not you will use it or whether or not you have a high Str. That does not change the fact that this is still an insanely powerful natural ability. This is nothing like HP or HD. You cannot compare the two. HD is something you get from experience. This you get just because you are. No player race should ever have an ability this powerful.
Lets compare this ability to some other players or player classes. Neither the barbarian (arguably one of the biggest powerhouses of the game) nor the monk (the best unarmed attacker of all, hands down) can possibly measure up to this. Barbarians are limited in damage because they can only do as much damage as the largest weapon they can wield. A monk can not do over 2d10 for its base damage even if it goes into epic levels.
I understand that Morganth is an epic character and should not be limited to what can be found in the DMG and PHB but anything new you add should be within reason. These claws are a natural ability that Morganth has just because he is and can do x amount of damage, again, just because he is?

in the hands of a starting character, it would do diddly squat to most things
: Do you have any idea what you were saying when you said this? A monk gets to do 1d6 dmg at 1st level (med size of course). A normal character only gets to do 1d4 with an unarmed strike. This automatically makes the character with this ability superior to any other character of equal level.
At 5th level, the character gets to do 5d6 dmg, which, if I am doing my calculations correctly, is more than a large sized monk at 16th level who does only 4d6 dmg. This is, of course, leaving out the fact that one of the most powerful weapons, the mercurial greatsword, only does 2d8 dmg (as stated in
Sword and Fist).
You cannot say that this ability is not unbalancing and you get this ability just because you are a wizard. Any DM that would allow something like this is just doing some bad DMing.
