Are there any mechanics to Chandrahas, or what determines how many walls he breaks down with Chandrahas?
Last night, he consistently broke at least 6 out of the 7 available walls (1 was broken during Butterfly phases) with Chandrahas, and this only left us 1 wall to handle the remaining 50% of his HP. In some rare occurrences, he broke all walls, and we were left with nothing to handle Pillars of Heaven, even in the smoothest buildups to Chandrahas.
I do not recall seeing this ever happened before last night's hotfix, and am wondering if this was a bug introduced by the recent hotfix.
