It would probably work better to have the class deal 1 Wisdom damage per day, rising by 1 at 4th, 7th, and 10th levels, unless the character makes a DC 10 + class levels + Wis modifier Will save or something.

That would make the Will save at 1st level 11 + Wis modifier (let's assume +4 for this example), for a total of DC 15 every day, on penalty of losing 1 Wisdom for the day.

At 4th level, it'll be 14 + Wis modifier (+4 again?), for DC 18, on penalty of losing 2 Wisdom for the day.

Of course, then you risk the absolute need for a restoration spell every few days if the character has an awful Will save.
