Cogsworth the Timekeeper Rogue

Cloak of Displacement. While you wear this cloak, it projects an illusion that makes you appear to be standing in a place near your actual location, causing any creature to have disadvantage on attack rolls against you. If you take damage, the property ceases to function until the start of your next turn. This property is suppressed while you are incapacitated, restrained, or otherwise unable to move.

Sneak Attack. Once per turn, you can deal an extra 3d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon. You don't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll.

Uncanny Dodge. When an attacker that Cogsworth the Timekeeper Rogue can see hits him with an attack, he can use his reaction to halve the attack's damage against him. 

Pendulum. Melee Weapon Attack: +8 to hit, reach 5 ft., 1 target. Hit: 8 (1d6 + 5) Piercing damage.

Heavy Crossbow. Ranged Weapon Attack: +8 to hit, range 100/400 ft., 1 target. Hit: 11 (1d10 + 5) Piercing damage.

Cunning Action. Cogsworth the Timekeeper Rogue can take a bonus action on each of your turns in combat. This action can be used only to take the Dash, Disengage, or Hide action.

Turn Back the Clock. Cogsworth rolls 1d4.to the unoccupied space nearest the position he occupied that many turns ago. If Cogsworth the Timekeeper Rogue were to be prone, grappled, or restrained he is no longer. Other status effects stay the same. Cogsworth the Timekeeper Rogue may do this once as a Bonus Action once per short rest.

Turn Back the Clock. When Cogsworth is targeted by an attack, he can use his reaction to roll a d4 and teleport to the unoccupied space nearest the position he occupied that many turns ago. The triggering attack misses. If Cogsworth is prone, grappled, or restrained, that condition ends. Other conditions affecting him remain. Cogsworth can use this reaction once, regaining its use when he finishes a short or long rest.
