What does this pull request do?

Smite of Rage is currently consuming between 2-3 shadows. It is a single hit weaponskill.
This change removes the random removal of 2-3 shadows as well as updates the mobskill script to align with current LSB standard.
Tested as Lv75 SAM on Aura Weapons.

Steps to test these changes
