Psionic Domination is an innate ability available to Mind Flayer creatures. The ability is initiated via script by the AI. The effect is directed at a single creature target in visible range of the source creature. The Domination will require the target to make a Saving throw vs. spell with a -2 penalty or suffer a Dire Charm effect that lasts 45 seconds. The effect is non magical and can't be dispelled. Once the effect duration has expired or otherwise been lifted, the target creature will revert to its natural allegiance, which will most likely be hostile to the Mind Flayer.
The Psionic Domination will bypass Magic resistance and cannot be blocked by spell protections such as Globe of Invulnerability or Spell Trap.
