Algha the Unbound

Legendary Resistance (2/Day). If Algha fails a saving throw, she can choose to succeed instead.

Adrenal Regeneration. At the start of each of their turns, the Algha regains 10 hit points and can end one condition on herself, provided she has at least 1 hit point.

Turn Immunity. Algha is immune to effects that turn undead

Denial of Death. If this creature is killed, they will reform using the body of a slain humanoid with their spirit, arising at the next dawn. If they are killed in front of their gravestone, they are forced with their own mortality, and their spirit moves on.

Bloody Motivation. If Algha is under half her hit points, her Adrenal Regeneration increases to 20 hitpoints and goes back to 10 when she is above half her hitpoints. She also gains advantage on all her attacks and can use a new reaction while her hitpoints are under half.

Multiattack. Algha makes three Greatsword or Longbow attacks. She can switch between the attacks easily and without need to drop or swap weapons.

Greatsword. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage, plus 7 (2d6) slashing damage if Algha has more than half of its total hit points remaining.

Longbow. Ranged Weapon Attack: +6 to hit, range 80/320 ft., one target. Hit: 5 (1d6 + 2) piercing damage, plus 7 (2d8) piercing damage if Algha has more than half of their total hit points remaining.

Second Wind (Recharges after a Short or Long Rest). The champion regains 20 hit points.

Atrocious Tactics. If Algha is under half her hitpoints, she can then make an attack with either her Greatsword or Longbow. If she hits, the target takes the damage and their speed is reduced to zero until the start of Algha's next turn. 

Algha can take 1 legendary action and only at the end of another creature's turn. The champion regains spent legendary actions at the start of its turn.

Rushing Cadaver Cleave. Algha runs down with her full movement and makes a shove attack against another creature. If this knocks them prone, she makes two attacks with her Greatsword on the target and adds 1d8 of necrotic damage with every successful attack.
