Anatomy of Powers
Some Powers have a "cost to use" listed at the top of their effects. To use the Power's effects, you must pay that cost. If you Repeat such a Power, you either pay the cost again, or the Repeat does nothing.
Some Powers have thresholds with an Energy cost listed alongside the Elements. You only need to pay the cost if you want to use that particular threshold; you may decline to pay and skip that specific threshold. If you Repeat such a Power, you either pay the cost again, or skip that threshold effect during the Repeat.
DO AS MUCH AS YOU CAN
When resolving a Power's effects, do as much as you can. If one part does not apply or cannot be done, skip it and do the rest. The only targeting restrictions are those in the target bar.
YOU CAN SKIP USING A POWER'S EFFECT
If you cannot or do not want to use a Power you've played - perhaps the board situation has changed - you're allowed to skip its effects entirely, as if it had a blank text box. If it was a Power Card, you don't get your Energy back, but you do still get to use the Elements granted by the card.
ONE LAND! ONE TURN! ONE USE!
- It only affects one single target land. "Destroy up to 3 Explorers" will let you destroy up to 4 Explorers in the same land - not in multiple different lands. If a Power has multiple effects, they ALL apply to the same land.
- It only affects the current turn. "Dahan have +3 Health" or "Invaders do not Ravage in target land" affect this turn only, not the rest of the game. Any permanent changes to the game will be represented by changes to a board - pieces leaving, Fear Markers moving, etc.
- It can only be used once this turn. You cannot choose to pay for a Power Card twice and use it twice. Innate Powers can only be used once per turn even if you have twice as many Elements as you need. If something makes a Slow Power Fast, you only get to use it during the Fast Phase, not both.
