Claws of the Hag
Feats
A hag-riven grows claws that are treated as natural weapons. These claws are primary attacks and deal 1d4 points of damage each (1d3 for a Small creature). At 2nd level, these claws are considered magic weapons for the purpose of overcoming damage reduction. At 5th level, the damage increases to 1d6 points (1d4 for a Small creature). At 9th level, the hag-riven gains the rend ability with her claw attacks. At 13th level, the hag-riven's claws threaten a critical hit on a natural roll of 19–20. At 17th level, the damage increases again to 1d8 points (1d6 for a Small creature) and the hag-riven's successful attacks with the claws inflict weakness on enemies. Weakness: Whenever the hag-riven hits a foe with her claw attack, the victim takes 1d4 points of Strength damage unless it succeeds on a Fortitude save (DC = 10 + half the hag-riven's level + her Constitution modifier).
