Change her mind control, so that it's an area around where you target it, and you can target the ground (think Nidus' 2). Enemies in this area of affect only target and attack other enemies in the targeted area. Moddable duration. Think of it as "I want this group of enemies to be taken out of the fight, and to kill each other".

Change Psychic Bolts to a two part ability. You can hold down the button to change which one will be cast. The first version fires psychic bolts outward. Bolts start on Nyx and spread outwards in a circle, pushing enemies and confusing them. The second version does the opposite, in that the bolts start at the "max" range of the circle and pull inwards, damaging and confusing enemies and pulling them toward Nyx. Think of it as "I want to get these enemies off of me and do some light CC to them", and the other mode as "I want to group these enemies together, light CC them, and have them ready to hit with my first ability".

Change this to a mass sleep. Enemies are knocked down, and stay down in a "sleep" until they are damaged. Moddable range and duration. The hit that wakes up an enemy deals increased damage. Think "I want all enemies around me to stop doing anything until I decide to wake them/kill them".

Change Absorb into "Psychic Counter". It would be a channeled ability, draining energy as you leave it on. Any enemy who attacks Nyx with a range attack becomes confused, changing targets randomly. Any enemy who attacks Nyx with a melee attack becomes Mind Controlled, only attacking non-tenno things. This would be active defenses, only allowing enemies to get a single hit (sometimes more, if the random target picks you) off on Nyx before becoming lightly CC'd. Confusion would last 5 seconds, Mind Controlled would last 10 seconds.
