Cost

Cost is a property of active skills. Most skills have a mana cost by default, though costs of life or other resources may also be possible.

The cost of a skill must be paid each time it is used. The cost of skills is spread over a short period of time as the skill is activated. Cancelling a skill mid-activation, such as with a dodge roll, will stop the remaining cost from being spent but will not refund any already spent cost.
