Control Spawn (3.5e Feat)
From D&D Wiki
Control Spawn [Undead]
Your victims serve you eternally in death.
Prerequisite: , Enervating Touch
Benefit: When a creature dies from the negative levels you inflict and rises as a Wight, it comes under your control. At any one time, you may control a number of Wights in this manner equal to your Charisma modifier (minimum of one). If you create additional Wights, you choose which spawn you lose control over.
