So apparently, if you hit first boss in tosh for more than 60% hp in a single hit (and hence bypassing a candle phase) the boss will glitch and become untargetable permanetly, the instance will appear as thought you are in candle phase, but boss will agro as normal.
i was hoping that using chiron i would be able to hit from out of agro range of the boss, doing 50% or more, then be able to hit a 2nd time.
this idea worked the first time when i hit 25% or so with a single hit, but when i strong summoned and used a few more cd, the boss glitched to this permanent dark phase.
during this, the boss will begin to use hard mode only skills, even on easy mode.
what did we learn from this: dont dps to hard or we cant dps at all
