Characters may now play cards or use powers that affect your check. (Remember that collectively, the party may play no more than one of each type of boon during a check, although powers that say they can be played freely do not count toward that limit.)
Some powers may allow you to replace a specific die with a different one. For example, Lini can activate a power on her Wild Whisperer role to roll a d10 instead of her Strength, Dexterity, or Constitution die.
Characters may not use powers that modify a skill when you’re not using that skill, and characters may not use powers that affect combat checks when you’re not attempting a combat check.
Cards played at this time do not add their traits to the check; for example, playing the spell Aid to add to a check does not give the check the Magic trait.
