Was a bit more difficult than I expected. Tried blue expert solo on auto. Raging overdrive hits harder than expected with a water team and trying to auto battle is a bad idea as auto battle has terrible AI, and because of that, will take longer to get it out of rage as it keeps recovering its rage meter and you don't want to eat multiple raging overdrives. Not much problem doing it on manual but I don't want to be running raid events on manual...
Was in a Ragnarok from the start. Got up to 14/30 people. Did not manage to get it out of rage even once after it got in the state.
