Alright, I just went to Zakum and tested against his lightning attack (that inflicts Seal).

Hit -> Concentration activated -> no Seal
Regular miss -> no Seal
Illusion Step miss (with the animation) -> no Seal
Hit -> Sealed

So yes, Illusion Step will now block attacks that inflict statuses I remember I always thought it was annoying that it had to be a regular miss to stop them before and IS's effect wouldn't block them.

Alright, that's good to hear. Yeah, that was annoying for classes with Dodge Rate skills, but for classes with only Evasion Rate like DB's, that was a huge advantage for them at a boss like Empress.
