Wow quite a run! Only final bosses cant get items atm, so it sounds like a Destroyer might have gotten a Bloodmist Mask which would be devastating D: That's a really smart strat boosting a stage 1 monsters HP before evolving it. Also my best run ever was using Parra as my main damage dealer by merging it with 3 Spell Vortices (one double, and another single) plus equipping a Heart of the Ocean. That plus a Tiz giving her tons of spd meant alot of Zephyr stacks for huge cyclones. I dont think double Mabek is stronger than other combos so Im not too worried (the main thing it does that others cant is enables Lucky). Im 90% sure Dying Breath doesnt stack, but ill have to double check. (Also there is a way to get 2 of the same monster during a run!)
Good Parra run, was only on normal mode but 9 loops! Never found enough hats to get Magical 2 too
