Augment Creature

Target a creature you are bonded with and choose either fire, cold, or lightning. Until the spell ends, the chosen creatures' attacks deal an additional 1d4 damage of the chosen type and that creature benefits from the additional damage provided by the hunter's mark spell on a marked target.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, choose an additional bonded creature for each level beyond 1st. If you cast this spell as a 10th level or higher Ranger, the additional elemental damage added is increased to 2d4. At 15th level or higher 3d4 and 20th level or higher 4d4.
