Life Cost
In certain circumstances, a portion of the Mana Cost when using skills can be replaced with a Life Cost.
If the conversion percentage is greater than or equal to 100%, this skill will only consume Life equal to the corresponding percentage of Mana. The consumed Life is not regarded as damage taken.
If the skill doesn't cost Mana, this effect will not apply to it.
