I have not gotten a single chest this festival. Normally I average 4-6 and I’ve been grinding for a similar amount of time, so it is easy to feel that the coliseum hates me. Despite it being an inanimate mindless object.
And then it decides to let my dragons land 3 sequential Rallied Eliminates on a Mantarune and have each one score a crit. Which turns out to be the precise amount of damage to have the boss die before it got a single turn.
Dear coliseum: you are giving really mixed messages.
