Armor of the Spectral Arm

• This armour's armor class is 15 with a maximum dexterity modifier bonus of 2.
• While attuned, the wearer can summon a spectral arm at will.
  • The spectral arm has the same capabilities of a normal arm
  • It can be retracted on will.
  • Unarmed strikes with the spectral arm deal necrotic damage instead.

Cursed. If the spectral arm has been summoned for more than 10 minutes, it will start to sneakily act on its own.
At first, it may do things like use a random object in the vicinity, touching somebody else while they are looking away or stealing from them and putting it in your pocket(it has a +5 on sleight of hand).
After being active for 1 hour, the armour grows powerful enough and attempts to control the wearer, to force it to do their bidding and become effectively their puppet.
The wearer needs to make a DC 16 wisdom saving throw every hour, on fail he becomes charmed and follows its commands.
On success, the control dissapears, and the wearer can act on its own again.

After the armour has been fully activated, it can only be reset by letting it bath in sunlight while submerged in clear water, or you splash holy water on it.

This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.
