Grief's Vengence

A bond was broken with violence, and now summon must pay...and so does anyone who gets in the way

Vengeful Determination: When you are reduced to 0 hit points but not killed outright, you can drop to 1 hit point instead. You can use this ability once per long rest.

Eyes of Retribution: You are able to cast Hunter’s Mark. You can use this feature a number of times equal to your proficiency bonus, regaining all expended uses when you finish a long rest.

Level 9

You can now maintain Hunters Mark for up to 8 hours as long as you maintain concentration. Damage die goes up to 1d8
