When you resolve a skill or ability, you must do as much of the skill or ability as is possible, ignoring any portion that you are unable to resolve. If the skill or ability has a cost associated with it, you must be able to fully resolve the cost in order to resolve the skill or ability. If a skill or ability is worded such that you must do one thing to do another, or do one thing then do another, the first portion of that skill or ability is considered to be the cost.
