K, this introduces a radical concept from d20 modern. Mutations that have mechanical effects. But now, lets expand the scope a bit. On one hand, we could just have pure humans be the only intelligent things around. In fact, this is what that is in a way.
The base is a normal 3.5 human. Nothing out of the ordinary. But, lets say you wanted to play a Elf. Easily done. Note, everyone gets 1 free LA of the Mutant Template under this system, or 10 mutation points free
First things first. What, mechanicly, makes a elf diffrent then a human? And not in cultual terms, but biological? The Elf is frailer, but more nimble. They can see better in dimlight and have keen senses. They don't need much sleep.
So, first off we have the abillity adjustments. A simple abilliuty burn to Con, and 2 Reverse Gene Therpy to Dex, and you have the abillity bonus/penalty of a elf.
Now, for the longevity. Simple to make a major mutation, that can be taken more then once, but it won't be a full elfen lifespan. Costing 4 points each, they increase their lifespan by (1.75*Number of times taken). Normaly, this is 3, resulting in a 5.25 multiplier to all age catagories. So middle age would be 183, old age would be 278, Vunrable would be 367 and max age would be 577. The Bonus feat normaly gained from bein g a human is replaced with the Bevololent Mutation feat. This gives them 3 more MP, and lets them grab the morphean template. They also recive lowlight vision as a Bonus Mutation.
So the Mutant Elf gains all the normal human features, and gains some addtional mutations.
Will be getting links and a table up soon.
Power restored for christmass. I'm back!
