Balthazar, Victarion of the Godwalker Herd

Reckless. At the start of its turn, Balthazar can gain advantage on all melee weapon attack rolls he makes during that turn, but attack rolls against him have advantage until the start of his next turn.

Extra Attack: Whenever Balthazar takes the Attack Action, he can make two spear attacks.

Spear. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit:  (1d10+8) piercing damage.

Spear. Ranged Weapon Attack: +8 to hit, range 20ft/60ft., one target. Hit: (1d10+8) piercing damage

Gore. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage.

Charge. If Balthazar moves at least 10 feet straight toward a target and then hits it with a gore attack on the same turn, the target takes an extra 9 (2d8) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be pushed up to 10 feet away and knocked prone.

Spear of the Stormlord. When Balthazar hurls the spear and speaks its command word, it transforms into a bolt of lightning, forming a line 5 feet wide that extends out from Balthazar to a target within 120 feet. Each creature in the line excluding Balthazar and the target must make a DC 14 Dexterity saving throw, taking 4d6 lightning damage on a failed save, and half as much damage on a successful one. The lightning bolt turns back into a spear when it reaches the target. Make a ranged weapon attack against the target. On a hit, the target takes damage from the spear plus 4d6 lightning damage. 

Once the spear has been thrown using this magical property, Balthazar can use a bonus action to call the spear back to him, or to magically teleport him to the spear. 1/Day

Opportunity Attack

 Shield Bash: When an enemy makes a melee weapon attack against Balthazar and misses, Balthazar can use a reaction to bash said enemy with his shield. Unless the enemy can on a DC 17 Strength saving throw, the enemy is shoved 10ft in a straight line backwards. 

Balthazar has 2 legendary actions per round. At initiative order 20, Balthazar can spend 2 of his legendary actions to do either of the following:

1. Gore. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage.

or 

2. Frightening Gaze: Balthazar fixes its gaze on one creature it can see within 10 feet of it. The target must succeed on a DC 18 Wisdom saving throw against this magic or become frightened for 1 minute. The frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target’s saving throw is successful or the effect ends for it, the target is immune to the creature’s gaze for the next 24 hours.
