Generated Skill choices and costs
Skill Potion offers three random Skills and adds the chosen one to hand, free for the current turn. The offered cards are not a guaranteed Block solution. A Skill may provide setup, retrieval, energy or another effect that needs the rest of the hand to be useful.
When the potion is meant to rescue a turn, use it before committing resources that its result might need. A zero-cost retrieved or generated card can still leave another card’s normal cost to pay. Read the offered text and target pile before assuming the whole sequence is affordable.
The discount lasts this turn, not automatically for every later play in the combat. If the chosen card remains available on a later cycle, do not assume its ordinary energy cost has permanently disappeared. Touch of Insanity has a different stated duration.
Draw restrictions still matter. A Skill whose benefit is drawing cards will not restore that benefit through Fiddle or a completed Battle Trance restriction. A card that adds or retrieves another card uses a different mechanism. For other ways to convert a potion into a safer current turn, read potion timing.
