Akali, The Rogue Assasin

Assasin's Mark. A creature marked with this feature emanates an invisible 10 foot aura that is only detectable by Akali. If Akali enters or exits this aura, the marked creature loses Assasin's Mark and Akali readies Fuji, making her next attack with her kama deal an additional 11 (3d6) slashing damage.

Evasive Mastery. When Akali makes a "dash" or "backflip" while using an action, all opportunity attacks against her have disadvantage.

Kama. Melee Weapon Attack: +9 to hit, one target. On hit, a target takes 7 (1d6 + 4) slashing damage. If Akali has Fuji ready, she deals an additional 15 (3d6 + 4) slashing damage

Kunai. Melee or Ranged Weapon Attack: +9 to hit, one target, range 20/100 feet. On hit, a target takes 6 (1d4 + 4) piercing damage.

Five Point Strike (Recharge 2-6). Ranged Weapon Attack: All creatures in a 5 by 10 foot rectangle must make a DC 17 Dexterity saving throw. On a failed save, a creature takes 33 (3d4 + 12) piercing damage or half as much on a successful save. Taking damage from this ability applies Assasin's Mark.

Twilight Shroud (Recharge 6). Akali throws a smoke bomb. Choose a point within 15 feet of Akali. A 30 by 30 foot ring of smoke appears in that area, with the innermost 10 by 10 feet left empty of smoke. While in the smoke, Akali may use a bonus action on her turn to become invisible. The ring of smoke lasts for 3 rounds. Akali loses her invisibility when she makes an attack. Additionally, if Five Point Strike is unavailable when Akali casts Twilight Shroud, she recharges it.

Shuriken Flip (Recharge 5-6). Make a ranged attack against target creature within 60 feet of Akali (+8 to hit). On hit, a target takes 14 (4d4 + 4) piercing damage and becomes marked for two rounds. When Akali throws the shuriken, she backflips, moving 10 feet backwards immediately. At the start of Akali's subsequent turns, she may dash to any one marked creature and kick them in the teeth. When Akali reaches her marked target, she may make a melee attack with +12 to hit. On a hit, she deals 17 (5d4 + 4) bludgeoning damage.

Perfect Execution (Once per Long Rest). Akali dashes to target creature within 30 feet. She deals 25 (6d6 + 4) slashing damage to that creature. At the start of her next turn, she may dash in a 15 by 30 foot line, striking all creatures of Akali's choice within that area. All creatures of Akali's choice within the line must make a DC 16 Dexterity saving throw. On a failed save, a creature takes 18 (4d6 + 4) + 1 for every 3 hitpoints the target is missing. Therefore, a creature missing 30 hitpoints will take 18 (4d6 + 4) + 10 slashing damage.
