Enduring Wallop

Paragon Tier
Prerequisite: 11th level, dwarf, fighter
Benefit: When you hit an enemy with a fighter daily attack power while wielding an axe, a hammer, or a pick, that enemy takes ongoing damage equal to your Constitution modifier (save ends). If the power already deals ongoing damage that has no damage type, instead increase that ongoing damage by an amount equal to your Constution modifier.
