As far as I know, when he disguised as Momon, he merely wore the armor and wield swords created with Create Greater Item, which is not restricted on his magic caster class despite being warrior equipment, thus, he can still use some spells like Create Mid Tier and Low Tier Undead but not Fly spell as some of his spell types are limited when he wear that armor made with magic. The only time he used Perfect Warrior transformation was when he fought Shalltear and Jaldabaoth. In Perfect Warrior state, he cannot use magic at all, which is why he didn't use it everytime he went on adventures as Momon, only on special occasions like when he fought Jaldabaoth.

Anyway, it is true that after his battle against Clementine, he paid more attention to his fighting style and becomes more skilled with weapons as even Shalltear is pushed into a corner for a second during their melee battle.
