1) There is a blessing in the Hourglass that lets you bury a card to reroll a die. Can you do this multiple times during the same check (in fact, can any Hourglass blessing effect be used multiple times)? I'm assuming it doesn't count as a boon for "one boon of each type per step"?
1a) The "you" in the Hourglass blessing effect refers to any player, not just the active player, right? (e.g. "You may reroll any die showing 1", and my friend is avenging my failed boon ---> he would get to reroll 1's)
2) Wall of Light:
Display. While displayed:
For your combat check, you may use your Arcane or Divine + 2d4, or 2d8 if it is against an Undead bane.
On another local character's combat check, add 1d4 and the Magic trait.
At the end of the turn, banish.
Is this banished the same turn you (dis)play it even if you don't use it, or does it remain displayed until you use it (then gets banished that turn)?
