"INTELLIGENCE: Not Ratable"
should we make anything out of that?
I agree with Demiurge. I think they were trying to be creative and state that its mind is beyond mortal means of classification. That kind of wackiness worked in 2E...but not now.

"When moving through earth, it can sense opponents through vibrations they create. It can detect a motionless opponent's heartbeat and breathing."
would tremorsense cover all of that?
Yes, and no. Vibrations...definitely. I'd say give it both tremorsense and blindsense.

"Severed limbs continue fighting (move 6) until the Abomination is slain."
Didn't trolls used to do the same thing, but now do not?

"The creature can be slain only in its home dimension. If reduced to less than 0 hit points elsewhere, the creature fades away and returns home, where it must rest for 2d6 hours before venturing forth again. To permanently slay the creature it must be reduced to -20 hit points on its home plane, and its remains must be doused with holy water and powder from the amulet that controls it."
We just did this with one of the angels....here we go...
Rejuvenation (Su): Lights may only be permanently destroyed on their home plane. If a light is reduced to -10 or fewer hit points on another plane, it dissipates and reforms on its home plane one month later.
Modifying that:
Rejuvenation (Su): The Abomination may only be permanently destroyed on its home plane. If it is reduced to -10 or fewer hit points on another plane, it dissipates and reforms on its home plane 2d6 hours later. Reducing the Abomination's hit points to -10 or lower on its home plane incapacitates it but doesn’t destroy it. However, dousing its remains with holy water and powder from the amulet that controls it will kill it.

"If the Abomination's Magic Resistance roll fails, spells are still turned as though the creature were wearing a ring of spell turning."
We can borrow this from the nerra:
Reflective Spell Resistance (Sp): A nerra has a special type of spell resistance that causes any targeted spell it successfully resists to bounce off and reflect back at the caster. The caster becomes either the spell's target or the point of origin for the spell's effect, as appropriate.
