Black ora

Your twohanded sword suddenly pulses, causing the area to be overcome with shadows. After a brief duration, the shadows begin to recede to the light and your vision returns.

The twohanded sword pulses in your hand, as if seeking something.

The shadows swirl around your twohanded sword.

The shadows surrounding your twohanded sword swirl around and a low murmuring can be faintly heard from within the gloom.

Bolts of greenish-black lightning spark from the shadow twisting around your twohanded sword.

For no apparent reason, you dive forward and hit the ground, covering the twohanded sword with your body.

The shadows surrounding your hand begins darken and contricts savagely!
  Your hand swells and turns purple, then explodes in a shower of blood!
   ... 20 points of damage!
   Bones from several fingers driven through your skin.
   You are stunned for 1 round!
