Armor of the Stone Sentinel

(Requires Attunement)
You have a +1 bonus to AC. You only need to eat
and sleep half as much as you otherwise would.
By remaining still and quiet for at least 10 minute
you gain advantage on Stealth checks to hide and
you get +5 to Insight, Investigation and
Perception checks.
Curse: Your skin becomes tough and stony, which hinders your movements and gives you -2 to Dexterity.
