Fighting Style: Interception or Defense

Cloak of Flies + Invisibility

Cloak of Flies
As a bonus action, you can surround yourself with a magical aura that looks like buzzing flies. The aura extends 5 feet from you in every direction, but not through total cover. It lasts until you're incapacitated or you dismiss it as a bonus action.

The aura grants you advantage on Charisma (Intimidation) checks but disadvantage on all other Charisma checks. Any other creature that starts its turn in the aura takes poison damage equal to your Charisma modifier (minimum of 0 damage).

Once you use this invocation, you can't use it again until you finish a short or long rest.

Invisibility
A creature you touch becomes invisible until the spell ends. Anything the target is wearing or carrying is invisible as long as it is on the target’s person. The spell ends for a target that attacks or casts a spell.
