Agnieszka's power drain

You cast a set of seven gaming dice at a target. The target makes a wisdom save. If successful, the target takes 7d6 psychic damage. On a fail, the target takes no damage. However, the caster rolls a d6. The affected character loses access to any ability requiring the use of a type of die, decided by the following chart:

1- d4

2- d6

3- d8

4- d10

5- d12

6- d100

The target may make a wisdom saving throw at the start of their turn to regain their lost abilities, or they gain them back after three turns.
