Requirements Sister Endreah is wielding an asp coil

Effect Sister Endreah is an expert at using her sword in close quarters. Her asp coil loses the reach weapon property, but she can make asp coil Strikes instead of fist Strikes when she uses Flurry of Blows. Claw of pain also applies to these asp coil Strikes when in this stance.

Claw of Pain

When Sister Endreah targets the same creature with two Strikes from her Flurry of Blows, she can cause lingering pain. If either Strike hits and deals damage, the target must succeed at a DC 21 Fortitude save or take 1d4 persistent mental damage (and become Sickened 1 on a critical failure).

Flurry of Blows (flourish)

Sister Endreah makes two fist Strikes, applying her multiple attack penalty as normal. If both hit the same creature, combine their damage for the purpose of resistances and weaknesses.
