Mark of the Unspoken

A mark granted by the Herald of Loss to a cleric of the Unspoken.

While marked, whenever you cast a spell that restores hit points, roll a d20. If the number rolled is less than your wisdom modifier (minimum of 1), you take 1d8 necrotic damage per level of spell you cast. This damage cannot be reduced in any way.  If one of the damage dice dealt by the mark is an 8, you can immediately cast one of the spells bellow that is of the same level as the spell that triggered the mark.

2nd- Darkness, Shadow Blade

3rd- Hunger Of Hadar, Summon Shadowspawn

4th- Evard's Black Tentacles, Shadow Of Moil
