Shining Break (3.5e Feat)
From D&D Wiki
Shining Break [General]
You can cause a brief fissure in an enemy you hit with a shining strike that serves as a weak spot.
Prerequisite: Shining blade level 3
Benefit: An enemy struck by your shining strike loses 5 points of damage reduction and suffer a -2 penalty to AC for 1d3+1 rounds.
Special: Do not calculate these effects on the shining strike that causes them. Multiple shining breaks do not stack. If an enemy has multiple sources of damage reduction, reduce each one by 5.
