Hmm, guess holidays means our intrepid wiki contributors take a bit longer to update. Going off the descriptions, it looks like it's...
Burst effect: reduce cooldown of the damage cut by 2 turns
Abi1: Atk debuff strengthened from -15% to 25% and cooldown reduced from 7 to 6
Abi2: Cooldown reduced from 8 to 7, also adds an atk buff?
Abi3: Duration extended to 2 turns, some water resist added
New passive: Randomly reduce the cooldown of the damage cut when damaged. Self burning from zeal counts.

So as far as defender awakenings go, it's closer to the Gaia side of things than Poseidon.
