Fixes #9496.

Description of the problem being solved:

The Grey Wind currently uses the life of the entity that is using it while it should be using the players life instead. Now it correctly looks at the players life instead of the life from the entity that is using it.

Steps taken to verify a working solution:

Check if player life increases the damage of Animate Weapon of Self Reflecting, Animate Guardian and Animate Guardian of Smiting
Make sure the weapon still functions properly on normal attack skills

Before screenshot:

Animate guardian uses its own life pool for damage (10% grey wind)

After screenshot:

Animate guardian now uses the players life pool for damage (10% grey wind)
