Problem
If a PC with the thorny hands corruption equips a one-handed weapon in his left hand, the @-screen and command to show melee damage of 'W'ielded weapons display the damage for both thorns and equipped weapon, even though the PC still only makes one attack.

How to reproduce it
1. Obtain the thorny hands corruption,
2. Equip a one-handed weapon in your left hand.
3. Press @ or Shift+W to check your melee damage.

Notes
Equipping weapons in the right hand, or two-handed weapons in either hand, work correctly.
