Terrormorphs - Mind Control Overhaul

Terrormorphs have fantastic lore behind them, but their gameplay doesn't reflect this. In the lore, they can dominate minds, but apart from a few scripted encounters, we never see this. This makes them play like reskinned deathclaws, rather than the apex predators they are in lore, toying with their prey's minds, rather than being just another tanky monster that charges you. This creation changes that by giving them access to a random pool of illusion spells to trick the player and make fighting them a unique experience.

Abilities

Illusions: They can summon illusions of themselves to distract you. These can't do damage, and will die in one hit, but they make keeping track of the real enemy difficult.
Invisibility: They can go invisible, making detection at a range a challenge.
Variable Speed: Their speed changes randomly, meaning you can track where they will be to hit them.
Mind Domination: You can be staggered as they attempt to dominate your mind.
NPC Control: NPCs can have various mind control effects cast on them. Calm, Fury, and Fear will be cast at random.
Scaling: Total health and damage done can be scaled up to a 300% increase if they are still not challenging enough.
