Strengthen Undead (3.5e Feat)
From D&D Wiki
Strengthen Undead [Divine]
You can give your undead allies a sudden boost of strength.
By spending one or more of your daily rebuke undead attempts, you can give a number of undead equal to your cleric level a bonus to their Strength scores equal to twice your Charisma bonus (if any). This effect lasts for one round per rebuke undead attempt spent. The undead must be within 60 ft. of you.
