The one with busted armor by Shalltear wasn't Momon's. It was Platinum Dragon Lord remote controlled an armor and act as one of the 13 heroes before. The armor was busted in Vol 3 by Shalltear,  though the story was told during the Intermission between PDL and Ridgrit, the latter said the armor looked busted, and PDL said it happened when he fought a vampire before (Shalltear).

Ainz as Momon is weaker than his spellcaster part, that's true, but his Perfect Warrior skill made him Lv 100 Warrior. If compared to Lv 75 and below (all enemies surrounding E-Rantel currently), it still a huge gap. And if I remember correctly, he has 2 way to turn into Momon I think he said that during his travel to the kingdom in Vol 5 or 6, and with demiurge in Vol 6, 1 with magic armor, 1 with perfect warrior. Up to Clementine fight, he used magic armor, so his stat, str, speed still like his magic caster side. While during and after shalltear, he changed to the perfect warrior mode, with increase in stats, speed etc, he moves and attack better. Otherwise I don't think his movement during Clementine's fight can impress Evileye when he fought Jaldabaoth. Evileye even mentioned his skill is far surpassing all that she know of, including those 13 heroes.

Another thing is, In Vol 6, he doesn't have any skill as a warrior, though to compensate that he used Frost Pain Modified as a skill. So I guess that's how he will grow as a warrior, he also ask Cocytus to check up his stance etc in Vol 7 during the battle with Foresight. And as a highest ranking Adamantite Adventurer, who knows what kind of magic item he has and can use like the crystal to use tier 8 magic.
