Traits

Ego: When any creature come within 15ft of Aldwith, your highest ability score is halved (rounded up) (If two or more ability scores are the highest, the DM may choose which one is affected). Additionally, all creatures have disadvantage on all saving throws. (These effects are only ended when you leave the 15ft space and all stat changes are reverted the moment you leave the space.)

Actions

Dreadful Slash: Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 36 (4d10 + 15) slashing damage. Special: If the Dreadful Slash reduces a creature to 15 hit points with this attack, it gains a bonus action to make an additional attack against any creature within range.

Crippling Shot. Ranged Weapon Attack: +10 to hit, range 100/500 ft., one target. Hit: 30 (4d8 + 7) piercing damage. In addition to the damage, the target must make a DC 20 Constitution saving throw. Empowered Debuff: On a failed saving throw, the target's Strength score is reduced by 1d8, and gains exhaustion. 

Reactions

Undying Will: When reduced to 0 hit points, instead of falling unconscious, Aldwith can choose to activate Undying Will as a reaction. For the next 3 turns, Aldwith remains conscious with 100 hit points and gains advantages on all attack rolls. After those 3 turns, Aldwith falls unconscious. 

Description

Aldiwth stands at 7ft, wearing his tattered armor. He once was the proud champion of the arena, undefeated for 3 years. Until he was finally defeated, where his soul could not rest and remained in the arena. Aldwith filled with rage, will attack any creature that enters the arena, hoping his prey would be the man that killed him in his life.
