Does Enervation make enemies lose their spells in Neverwinter Nights 2?

Neverwinter Nights 2 is a video game that widely adopts the rules of Dungeons&Dragons 3.5e, a tabletop role playing game. In D&D 3.5e, Enervation is a spell that makes the target get 1d4 negative levels if the caster succeeds in a ranged touch attack. This spell can be very powerful, since there is no saving throw, and it can wreak havoc on enemy spellcasters: each negative level they lose makes them lose their highest level spell slot. Additionally:

Each negative level gives a creature a -1 penalty on attack rolls, saving throws, skill checks, ability checks, and effective level (for determining the power, duration, DC, and other details of spells or special abilities).

However, since NWN2 often changes 3.5e mechanics when adapting them to the video game, I want to know if negative levels caused by the Enervation spell in NWN2 have the same effect.

Does the Enervation spell in Neverwinter Nights 2 remove highest level spell slots from enemy spellcasters?

Appendix: an example of losing spell slots

I cast Enervation on an enemy who has prepared Fireball (3), Haste (3), Web (2), Invisibility (2), Scorching Ray (2), True Strike (1), Magic Missile (1), Magic Missile (1) and Ray of Enfeeblement (1). In the tabletop game, if I roll 2 on my Enervation roll and the target gets 2 negative levels, it should lose its both highest level slots: Fireball and Haste. If I hit them again and roll 3 (and the target is still alive after gaining a total of 5 negative levels!), the target should also lose all their second level spell slots.
