Steps to reproduce

Find a high enough level RNG mob and get shot at a bunch, with and without Stoneskin, and cast a spell of a skill granted only by your sub job.

Expected behavior

Mob ranged attacks should not be able to interrupt your casts, nor should mobskills that get absorbed by Stoneskin (provided that they do not inflict a status that would interrupt, of course).
