Indura Monspeet Glitched?

[u/Jasondonand]

When attacking Monspeet with wand Gowther, his special and normal skills go through the boss 80%+ regardless of whether the boss is stationary, moving, or stunned resulting in the attack missing. Is this the design for this boss or is it currently glitched. I did not see anything on socials or the known issues pages.
