Only the 1st strike of Corvus's special 2 is unblockable?

Deli

So, in aw fighting a domino with the dodge defensive tactic she unsurprisingly evaded my special 2. The first 2 strikes missed her, but the final strike made contact. To my surprise tho, she successfully blocked the final strike. Is this working as intended? *Also would like to note she is unduped and the "unblockable" sign did pop up.

Domino probably reduced the ability accuracy of it and caused it to fail

Okaythen

Domino reduces AA of all abilities so there was a chance for the unblockable to fail Sometiems the power drain will also fail

The ai has a 99% chance of things to fail. Its 2% when you are using domino.
