See with the reduction I believe it was clarified to be that you shave 80 damage while in yang state from physical clashes, regardless of how much damage the technique you're clashing with does. I think it USED to be that if you take more than 80 damage you take the full damage. had to go back and read the fight between Serpent and Shady. Plus it says "capable of reducing damage from all physical clashes by 80 damage". I think that's what drackos clarified with the previous update.
Now for Onibi, the very last yang technique I have to learn. Finally. Onibi is a technique that passively activates when you enter yang state, and augments all of your creation by infusing them with change into hell. This not only breathes life into them but also grants two random mutations, which are decided by Tatsumaki in the official rolls channel. These mutations include increased vitality, increased speed, damage reduction, increased chakra reserves, and a number of others. These mutations expire along with the sentience the technique was granted once yang state ends, as that also brings Onibi to an end.
