Mr.Satan said:I've revised Assimilate to fall more in line with Digestio. It's more useful now and allows you to absorb any single aspect of your opponent, rather than just an ability score. I have a feeling that may have been Krusty's original intention anyway.
Assimilate (Su)
Absorb aspects of opponents you consume.
Prerequisites: Con 70 (or Cha 70 if Con - ).
Benefit: You gain one aspect of each opponent you defeat and consume.
This can include HD, an ability (no greater than esoteric), or an ability score.
e.g. If you defeat an opponent...
...with more HD, your HD increase to equal it's HD.
...with more Str, your Str increases to equal it's Str.
You can choose any aspect you are aware of, randomly, or no aspect.
Mr.Satan said:Bardic music as a bard of a level equal to your HD...Divine...or Cosmic. I'm guessing Cosmic? I ask because a character of mine with Assimilate is going to devour a Tulani to obtain that ability.
Mr.Satan said:Assimilate question...
If you die, and are brought back by cosmic string or some similar ability, do you lose your assimilated abilities...or are they a permanent part of you, having been...assimilated rather than borrowed or stolen?
