The SRD description for Seed: Transform is confusing when it comes to mental abilities (see bolded parts below):
The transform seed can also change its target into someone specific. To transform an object or creature into the specific likeness of another individual (including memories and mental abilities), increase the Spellcraft DC by +25. If the transformed creature doesn’t have the level or Hit Dice of its new likeness, it can only use the abilities of the creature at its own level or Hit Dice. If slain or destroyed, the transformed creature or object reverts to its original form. The subject’s equipment, if any, remains untransformed or melds into the new form’s body, at the caster’s option. The transformed creature or object acquires the physical and natural abilities of the creature or object it has been changed into while retaining its own memories and mental ability scores.
Mental abilities are defined in the description as follows:
Mental abilities include personality, Intelligence, Wisdom, and Charisma scores, level and class, hit points (despite any change in its Constitution score), alignment, base attack bonus, base saves, extraordinary abilities, spells, and spell-like abilities, but not its supernatural abilities.
I'm not quite sure how to interpret this. It seems like if you don't assume the likeness of a specific individual then you get none of the mental abilities quoted above, whereas if you do assume the likeness of a specific individual then you get all of them.
As an example, it sounds like if I transformed a level 20 lawful good dwarf fighter into a generic lich, his type would change to undead and it would gain the STR/DEX/CON of a lich but he would remain a lawful good fighter with his normal HP, saves, base attack bonus, INT/WIS/CHA scores and extraordinary abilities.
But if I transform him into a specific lich (with, say, 20 wizard levels), now the fighter is in every way identical to the lich, except for the fact that the epic spell may not give him the lich's supernatural abilities and that the transformation can be dispelled. He is now an evil lich with 20 wizard levels and a totally different personality/memories, has the STR/DEX/CON/INT/WIS/CHA of that lich, rerolls all his HD as d12s, etc...
Is this right?
