Amulet of Stolen Valor

An Amulet with a color changing gem in its center, it radiates an aura of 10ft from itself. Once activated it copy's an aura from the table below (Roll a D4)

1. Aura of Devotion - You and your allies have immunity to the charmed and fear conditions
2. Aura of Alacrity - You and your allies have their speed increased by 10ft
3. Aura of Warding - You and your allies have resistance to Necrotic, Psychic and Radiant damage
4. Aura of the Guardian - When an ally takes damage use your reaction to take it instead

Once you use the Amulets power it lasts until you fall unconscious and it cannot be used again until you complete a long rest.
