A Psicrystal As An Ancestral Relic? What?

[Rubik]

I'm taking the Ancestral Relic feat and I want my relic to be my psicrystal. I've gone past the idea of turning it into an all-purpose ioun stone (since I already have all of them I want anyway), and so I'm here to ask the question: what enhancements and abilities would go well with an all-purpose pet rock? Everything from magical traps to lifting off weapon enhancements, what would YOU do with a free 380,000 gp in ancestral relic psicrystal?

A psicrystal is a creature, not an item, and can't be a relic.

What level of cheese and/or optimization?Extremely high.

For reference, I'm level 20 gestalt, have done your aleax trick, have used illithid savant, and have refined my magic item crafting to the point where I have nearly 200,000,000 gp in magic items available.

A psicrystal is a creature, not an item, and can't be a relic.Well, in this case the stone I used to create it was an item before it was a creature, so it counts in this particular instance.

That or we could do a Haunt Shift trick. There's a spell that makes a creature count as undead for the purposes of spells and effects, so it totally works.

Just go with it, 'kay?
