Ninja - Rethinking how you play by mechanic design

[Ilyn]

Assuming you're talking about the ninja opener in the 2nd post, it's not wasted. The 30% is applied to the following Hyosho Ranryu

and what about that next cast after that? You still get another buff, the only way you won't be wasting it is to cast TCJ after it , it'll be gone by the next mudra cycle since it's 15 only seconds
