Couldn't see this one in the FAQ.
Can you use an character power more then once?
Example:
Lini: You may reveal an ally with the Animal trait to add 1d4 (+1) (+2) to your check. (this would require multiple animals if possible, revealing a Crow and a Dog)
Seelah: You may discard the top card of your deck to add 1d6 (+1) to your check. If the top card was a blessing ( or spell), recharge it instead of discarding it.
If you cannot, why does the bard specify differently?
Lem: ONCE PER CHECK, you may recharge a card to add 1d4 (+1) (+2) to a check attempted by another character at your location.
