Hi there,

I'm trying to create the Zendikar Vampire race (from the Plane Shift Zendikar UA) for use by my players and I'm having trouble putting the "Blood Thirst" racial in.
For reference:

Blood Thirst. You can drain blood and life energy from a willing creature, or one that is grappled by you, incapacitated, or restrained. Make a melee attack against the target. If you hit, you deal 1 piercing damage and 1d6 necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken, and you regain hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. A humanoid killed in this way becomes a null (see “A Zendikar Bestiary”).

I've got 1 point piercing (Damage - Piercing, Fixed Value: 1), 1d6 necrotic (Damage - Necrotic, 1d6) but no way to link healing to the amount of Necrotic damage dealt nor making the necrotic damage stick until long rest. In addition, the latter part of the effect with turning the victim has an awful lot of flavor- I likely can't put this as a modifier.

If anyone has any suggestions regarding how to make this ability work within the race creator I'd highly appreciate it.

It's unfortunate that any UA content prior to Jan 2018 can't be submitted publicly because a lot of the MTG conversion stuff was really cool (and someone else has likely already done this work for me).

Thank you,
null
