The Bubbles seem to be a Skill instead of a blight. So far we've seen it on Tamamitsune and Yukumo, and I think one other. It seems to be kinda like Seregios weapons, where it activates after a number of rolls, and seems to affect Evasion (like more invincibility frames).

It's one of those things that's hard to gauge cause they've been throwing out weird info throughout the streams.
