I dont know if its intended, but upon body contact with ravanna, only meso guard is dispelled. Occasionally it is not dispelled by body contact. It has led to me dying when i get hit by 1/1 right after getting knocked into the boss body, which would have been non-lethal before this graphics change from Ergoth.
Are you sure it's not your MesoGuard running out? It could be Rava casting Mana Negation, but since you said only MG is dispelled i guess that's not the case.
it wasnt. I noticed it multiple times before I died. Recreated it on the spot as well, at the time it occurred. Gimme some credit.
Almost every time when Meso Guard is claimed to be "dispelled randomly", it's due to the player running out of mesos to tank the hits.
