I find his turncount extremely dubious too...i had worse or equal turns to him and i had mia/rolf AND mist. I know its normal mode, but theres not enough bexp to insta-promote a unit like mist who starts at lv.1 and cant see much combat due to being frail.Plus, she sucks at combat, i find extremely dubious that a mist can 4 turn 3-5 let alone survive the paladin horde. Theres also the things rfof and sal pointed out. Mist cant promote with a crown and thanks to canto and sol, celerity+pass is impossible.
Oh and 3-e is imposible too. I had marcia rolf mia ike mist and ranulf and i still struggled to get a 5 turn. 3-10 is imposible too...sigrun being able to equip celerity pass too in 3-11. Wtf must be a broken game or i call bull...
