We did this on purpose. For this boss we wanted to have all the items set at the same number of attacks so 18 seemed reasonable over a 13-day period. Now on the last day, if boss is still alive, players can attack the boss with stamina sliders like regular bosses (5 attacks at once) every 15-min. So hitting that 18 should be fair for everyone.
Defeated Boss In:6:08:05:42 I did 9 attacks and get no rewards. It is possible to give it more life for it can resist a little longer?
That's an option. It could be done so you can attack it with the slider once it's health gets below a 20%
i barely got 19 hits on the last one before it died and 17 on the one before it, feel cheated, got nothing it dies too qwik
