DCC/Mirror of Fates

Gaze into the mirror for one turn (10 minutes) and gain insight into your fate for the next half hour. During this time you may spend your action to ponder a choice you’re about to make (such as whether to enter a room or turn back) - there is a 75% chance of getting a sense of either weal or woe for you personally. If you do, you additionally gain a +4 bonus to any single attack roll, skill check or saving throw you make during the very next round, should you make one. There is a 25% risk of only getting a sense of uncertainty (and no bonus), but this means the magic remains active - you might ponder another choice, until you gain some insight into your fate or the time is up. Note: most choices involve both danger and reward, and the sense you get (weal or woe) is a best guesstimate.
