"Evil presence, my favourite spell, make them fall upon their knees or send their bones to hell" - Quaver on the Evil Presence Spell
Evil Presence Spell is the inherent ability of the Overlord's stronger will to dominate (subdue) or even destroy others in Overlord II. The corresponding spell is called Lighting Whip Spell.
It allows the player to enslave an innocent citizen by emanating enough evil power to make them worship the Overlord. Or kill them by overcharging with dark energy. Evil Presence is needed to enslave the two main towns of the game, Nordberg and Everlight. There are several advantages to enslaving a town: The enslaved will mine for gold, produce equipment for minions, and even create Lifeforce. In Nordberg, the villagers can breed seals for you to steal Lifeforce from. In Everlight, the elves and citizens can be bartending for your minions.
Use and Function
The 'Evil Presence' spell, a perfect mixture of Torture, Enslavement, and Death. When a target is blasted by the spell, it causes unimaginable pain, but when a target is held under the spell for a short moment, the spell turns the target into a loyal slave, bound to the Overlord's evil will. Finally, if a target is held under the spell for entire duration, it results in death, reduced to ash and lifeforce.
Like other spells in the game Lighting Whip is effected by your level of Corruption, more destructive tendencies will up the kill efficiency.
