Sleuth’s Shadowcoat

Wondrous item, uncommon (requires attunement)
  Sometimes a detective’s best tool is remaining undetected. The sleuth’s shadowcoat allows its wearer to take full advantage of shadows, to hide in plain sight, and to disappear in a puff of smoke (well… fog) when things go awry. Also, it has plenty of secret and obvious pockets in which to store things. Very useful.
  This item has 10 charges and regains 1d6 + 4 expended charges daily at dawn.
  Shadow Stealth. While in dim light or darkness, you can expend 1 charge as a bonus action to turn invisible until the start of your next turn. If you use your bonus action to spend 1 charge at the start of your next turn, this effect continues without interruption. This invisibility ends if you become brightly lit, or if you attack or cast a spell.
  Hide in Plain Sight. As an action, you can spend 2 charges to cast the chameleon skin spell (see The Appendix) on yourself.
  Disappearing Act. As an action, you can expend 2 charges to cast the fog cloud spell centred on yourself, and immediately move up to half your speed. Fog cloud has a duration of Concentration, up to 1 minute, when cast in this way.
  Rare variant: Increase the number of charges to 15 and the recharge to 1d10 + 5. The Shadow Stealth property changes so that you can activate it under any lighting conditions except bright, direct sunlight and it doesn’t end if you become brightly lit.
  Very rare variant: Increase the number of charges to 15 and the recharge to 1d10 + 5. The Shadow Stealth property changes so that you can activate it under any lighting conditions except bright, direct sunlight. In addition the invisibility doesn’t end if you become brightly lit, attack, or cast a spell. When you activate the Disappearing Act property, you can spend an additional 3 charges to cast the gaseous form spell on yourself immediately before you move.
