Vampiric Exultation

Planes and Subraces

Three of the races of Ixalan—goblins, merfolk, and vampires—are also found on Zendikar and appear in Plane Shift: Zendikar. They are presented here as races unto themselves, but in effect, the vampires of Ixalan and the vampires of Zendikar can be treated as two subraces of the same vampire race.

The core merfolk race presented here is the same as the one in Plane Shift: Zendikar, so green and blue merfolk are simply additional subraces.

For vampires, these traits presented in Plane Shift: Zendikar are features of the Zendikar subraces of vampires:

Ability Score Increase
Your Intelligence score increases by 1.
Null Transformation
A humanoid killed with your Bloodthirst ability becomes a null.
The Ixalan vampire's increase to Wisdom and Feast of Blood trait are features of the Ixalan subrace.

For goblins, each of the Zendikar subraces gains the following traits:

Ability Score Increase
Your Constitution score increases by 2.
Grit
You have resistance against acid and fire damage. In addition, when you are wearing no armor, your AC is equal to 11 + your Dexterity bonus.
The Ixalan goblin's increase to Dexterity and Agile Climber trait are features of the Ixalan subrace.
