Can an ability that has a cost be used more than once in the same timing window?

Question

Accepted Answer

Yes. If the ability asks you to pay a cost (discard a card, spend inspiration, deplete something) you can pay and resolve it again as long as you are still inside its timing window. Rending Claws and Misty Mountains Cold work this way. Abilities with a fixed number and no cost, such as Self-Sufficient, are limited to that number per instance, and single-trigger "before" or "after" abilities resolve once per trigger.
