Spell info:

Many Azlantian records depict Azlantians assisted by servents of the earth. Blessed by Desna, goddess of the moon and the world shaper. You gain the service of an Azlantian familiar, the servent takes an animal or beast form of your choice, up to cr 1/2. If a form is not chosen, its appearance is random. Appearing in an unoccupied space within range, the Azlantian servent has the statistics of the chosen form, though it is a construct instead of an animal or beast. The construct appears similar to the beast chosen by the Azlantian however appears to be made of stone, with patterns and runes carved across its body, its eyes also glow a pale blue.

The servent acts independently of you but always obeys your commands. In combat, it rolls its own initiative and acts on its own turn. The servent can take any action that the chosen beast can. When the servent drops to 0 hit points, it ceases to be animated, crumbling back into the earth from whence it came. It reappears at the start of every day, assuming that there is exposed earth to come from. (Ex, the Azlantian servant cannot be summoned on a cloud, ice, wood etc.)

As an action, you can tell your servant to pass through the earth. Until your next turn, your servant gains a burrow speed equal to its movement speed, allowing it to move unhindered by terrain. While your servant is within 100 feet of you, you and any other designated allies may communicate with it telepathically. Finally, when you cast a spell with a range of touch, your servant can deliver the spell as if it had cast the spell. Your servant must be within 100 feet of you, and it must use its reaction to deliver the spell when you cast it. If the spell requires an attack roll, you use your attack modifier for the roll.
