Seer's Bowl

''Peering into the crystal clear waters contained within this silver bowl, you glimpse fleeting fragments of the future. You see the day ahead of you, merely still images or small cuts of motion, in some cases entire uninterrupted minutes. With this knowledge, you can prepare, you can be ready.When you look away from the bowl, you forget most of what you've seen, like waking from a deep dream, but that knowledge is still there if you can reach out and grab it.''

Wonderous item, requires attunement by a spellcaster
Once per day, you can expend a 2nd level spell slot to peer into the bowl. After ten minutes, you may roll 1d20 and record the result. Whenever a d20 is rolled and you are directly involved in it, you may replace that roll with the recorded result. (Attack rolls, saving throws, or skill checks, you make or an enemy makes against you.) Multiple characters may be attuned to this item and use it
