Dimitri's wave of sorrow

Emitting a mournful and disturbing wail, you send out a pulse of magic imbued with sorrow.
All that can hear the caster and within the area when the spell is cast must make a wisdom save, on a fail they take 1d8 psychic damage and for the duration take a -3 penalty on attack rolls and saving throws. attacks against the creature have advantage.

For each spell slot used to cast this spell higher than 2nd level, the duration grows by 1 round. After the first round creatures affected by this spell can make another saving throw at the end of their turn. Also for each spell slot used to cast the spell the penalty grows by one, reaching a maximum on -10 at 9th level of casting.
