Viklander's Cube
It was made by Hampus Viklander, a mind flayer that is now apart of Comoedia Divina. This was a gift to an old friend but it appears it was taken or given away to the Feywild Keeper. How it works is to turn the thing a few times and a random spell comes out with no concertation required from a random spell list
For spell list, roll a d8
1- Bard
2- Cleric
3- Druid
4- Paladin
5- Ranger
6- Sorcerer
7- Warlock
8- Wizard
For spell level, roll a d10, 1 is a cantrip and 10 is a 9th level spell than roll a unique dice to pick a random spell from that level
