Primordial Transformation Boons

Elemental Form
Your Constitution increases by 2 and your Wisdom score increases by 1. An ability score cannot be increased beyond 16 this way. You become an Elemental in addition to any other creature types you are. Spells and abilities that affect Elementals of a specific CR do not affect you.

Primordial Affinity
While able to control all elements, your Primordial birth was sparked by one particular element: your Primordial Affinity. Your body is infused with malleable elemental energy. You must choose an element below and gain all the benefits of that element:

Water. You have resistance to cold damage. In addition, whenever a creature regains hit points due to a spell or feature you control, you can imbue them with healing elemental energy. The creature regains additional hit points equal to 1d6 + your Constitution modifier.
