*raaage*, tried expert mask dungeon as ghetto zombie team ( red ogre, 4x red masks, 5* siren ) and got all the way to the end, where I get two synchronised timer masks and a mystic mask. *sigh*, got one dead, and the mystic to 2 life before they attacked together. So much time, so much pain ;p
Have to farm up an echidna or something I guess, although I still see it as being a bit iffy - I'd used up pretty much all my stored gems when I died before, so an extra 3 turns may not have helped. Actually, shit, now that I think of it, taking my newbie dino rider probably would have helped ;p
