Sabotage freeze does not work with NPCs

[Aia del Mana]

From some testing, it appears that sabotage_e=freeze does not stop freeze from affecting the enemy creatures. This is evident from a combat log; merely attack into a created NPC ritual with a creature with freeze, and one shall find an enemy creature frozen.

I believe this is likely why so many were able to defeat the Battle Master at the Road of Battles, even with a x777 multiplier.
