Corpse Armor (Spell)

Corpse Armor is a 3rd level Necromancy spell cast upon a creature's fleshy corpse, creating an undead suit of armor. If a willing creature does not wear any armor, its AC becomes 15 + DEX. The armor emits a stench, forcing a CON save by any creature within 5ft or become Poisoned.

==Description==
You touch the corpse of a creature with flesh, partially animating it into an Undead Suit of Armor. The armor instantly clambers onto a willing creature not wearing armor within 5ft of it upon casting this Spell. The target's AC becomes equal to (15 + it's own Dexterity modifier).
The Corpse Armor emits a fetid stench, forcing any creature other than it's wearer to make a Constitution Saving Throw when within 5ft of it at the start of its turn or become Poisoned (Condition) until the start of its next turn; the Constitution Saving Throw is made using the Spellcaster's Spellcasting DC. 
A creature that successfully saves against the Constitution Saving Throw is Immune to the Poisoning Effect of this Spell for 1 Hour. 
The Corpse Armor remains animated for up to 24 Hours, where it then withers into a pile of fetid flesh. As long as this Spell is casted again on the Corpse Armor within the 24 Hour period, you may extend the duration of the Corpse Armor. The Corpse Armor becomes inert if it's bearer dons armor, or if you dismiss this Spell as an Action.
