D&D Armory 004 - Scarab of Protection

A little late on this one, but it was fun to work on and I'm mostly happy with it.
*****
If you hold this beetle-shaped medallion in your hand for 1 round, an inscription appears on its surface revealing its magical Nature. It provides two benefits while it is on your person:

• You have advantage on Saving Throws against Spells.

• The scarab has 12 Charges. If you fail a saving throw against a Necromancy spell or a harmful effect originating from an Undead creature, you can use your Reaction to expend 1 charge and turn the failed save into a successful one. The scarab crumbles into powder and is destroyed when its last charge is expended.
