What's an easy way to change your type to Aberration? I'm of course asking if you already made your character and is past lvl 1, so no creating character with templates slapped on. I mean feats/classes/etc... The easier the better.
Becoming an aberration is really hard, even with templates. The arachnid creature template from Underdark is about the only thing that does it.
But Arachnoid Creature is restricted to Animals, Beasts and Magical Beasts IIRC... So it's mostly a No-Go. IF only it could be applied to Humanoids/Monstrous Humanoids... Then Incarnate Construct Warforged Feral Arachnoid would be SICK, but it's pretty hard to make Magical Beast PC characters, the only i can remember are the Beguiler from Shining South, and Awakened Animals. Insectoid Creature from Savage Species is LA +2 and gives Aberration template, it's also less restricted. But templates are DM-Approved, and it's pretty hard to buy out that +2 LA... Losing 2 class levels hurt. I perused most of the Lords of Madness/Elder Evils books, since i recalled a feat that gave the Aberration template, but no luck. Maybe the feat i'm recalling is from some dragon/dungeon magazine? I'm pretty sure there's a feat somewhere that has the Aberration Blood feat as pre-requisite, but actually makes you an aberration.
Another question: Is the Effigy template a legal target for Incarnate Construct? If so, can i use to make a PC? :O (Google search results give mixed opinions)
