Odin countdown: Illusion

Illusion

The feature where level caps don't result in a hard cutoff but an increasing failure chance the higher the target's level is above the cap.

Level caps are increased in general and command/image spells were added, making illusion actually viable.

In addition to mind affecting spells, there are a few sneak attack buffs and sneaking buffs that should enable more gameplay than "you now sneak X% better" in other spell packs.

Antimagic is more useful than in Apocalypse. You don't need to get the timing right, just break through their ward (remember wards got buffed) and drain their mana when you have a clear shot. Mana drain spells come with stunted regeneration so they don't regenerate it all back immediately and you can actually shut down casters effectively.

Vokrii includes new perks to buff command spells for a total of 18 perks (the cap, due to VR compatibility). I'd do the same for Ordinator, but I'm not sure if there are compatibility patches that include the illusion tree, will never be updated and may therefore prevent me from changing it.

Staves and scrolls are no longer useless.

There are more master spells, but only where they would create value.

Illusion traditionally has multiple levels of similar spells. This is probably the school with the most "straight upgrades". This is probably unavoidable because players may not use perk overhauls and level capped spells have a tendency to become completely useless if they don't scale up.

This school is not entirely finished yet, especially the triplicate Simulacrum spells.
