If the opponent lets him survive that long, and he has the equipment to leverage it.

Normally, a level 100 opponent should be dead two or three times over before a level 100 magic caster is out of MP. This was true even for Shalltear, who was in many ways optimized against necromancy, she lost a clone, her summons, and had to use an auto-resurrection equipment to still be standing when Ainz used Perfect Warrior. Furthermore, he wasn't even particularly low on MP, it was just that his plan had reached that stage already.

Nor would he have done very well without access to specialized warrior equipment switched in on the fly by use of cash items.

The reason that Ainz was still standing was because he tricked Shalltear into relying heavily on Divine-type damage, after having made himself immune to it (he bluffed her that closing to inflict Bludgeoning damage would trip traps, and that he had made himself immune to Fire damage). Otherwise she'd have already killed him due to his relatively low HP (unless he escaped, he later mentioned having made a plan for that if he failed to trick her).
