Desiccate (Spell)

Dessicate is a 2nd level Necromancy spell that drains the target's moisture, forcing a CON save and dealing 4d8 Necrotic damage (half on success). 
__TOC__
==Description==
You magically drain the moisture from a creature in range. The target must make a Constitution Saving Throw or take 4d8 Necrotic damage, or Half as much on a successful Constitution Saving Throw. On a failed Saving Throw, you may choose to imbibe the moisture from the target, which is considered to be 2 Gallons of Water; on a success, you may only choose to imbibe 1 Gallon of Water from the target.
This Spell has no effect on Undead or Constructs.
If you target a Plant-Like Creature or Magical Plant, it makes the Saving Throw at Disadvantage and the Spell deals Maximum Damage to the Plant. If you target a Non-Magical Plant with this Spell, such as a Tree or Shrub, it automatically withers and perishes.
