Argax Trueflame

Aura of Protection. Argax and his allies in an aura of 10ft around himself gain a bonus to saving throws equal to his Charisma modifier (+2) so long as he is conscious.

Aura of Alacrity. Argax's Speed increases by 10 feet. In addition, whenever an ally of his enters his Aura of Protection for the first time on a turn or starts their turn there, the ally's Speed increases by 10 feet until the end of their next turn.

Defense. Argax gains +1 to AC when wearing Light, Medium, or Heavy armor.

Channel Divinity (2/Day). Argax may use either his Inspiring Smite, Peerless Athlete, or Divine Sense using one charge of channel divinity.

Inspiring Smite. Immediately after Argax casts Divine Smite, he can expend one use of his Channel Divinity and distribute Temporary Hit Points to creatures of his choice within 30 feet of himself, which can include himself. The total number of Temporary Hit Points equals 2d8+7.

Spellcasting. Argax is a 7th-level half-caster. His spellcasting ability is Charisma (spell save DC 13, +5 to hit with spell attacks). He can upcast spells using his higher level spell slots. Argax has following Paladin spells prepared: 
1st level (4 slots): Command, Cure Wounds, Detect Magic, Divine Smite (1 free use per day), Guiding Bolt, Heroism, Searing Smite, Shield of Faith
2nd Level (3 slots): Enhance Ability, Find Steed (1 free use per day), Lesser Restoration, Magic Weapon, Shining Smite

Multiattack. Argax makes two attacks that can be with either his Longsword or his Fire Breath.

Longsword. Melee Weapon Attack: +7 to hit, reach 5 ft. Hit: 9 (1d8 + 4) Slashing damage. If a creature is hit with his Longsword, they have disadvantage on attack rolls until his next turn.

Fire Breath (3/Day). Argax exhales fire in a 15-ft. Cone or a 30-ft. Line that’s 5 ft. wide. Each creature in that area must make a DC 14 Dexterity saving throw, taking 11 (2d10) fire damage on a failed save, or half as much damage on a successful one.

Dragon Fear. Argax can expend a use of his Fire Breath to roar, forcing each creature of his choice that can hear or see him within 30 ft.to make a WIS saving throw (DC 13). On failure, a target becomes frightened of him for 1 minute, or until it takes any damage (repeating the saving throw, ending on success).

Draconic Flight. Once per Long Rest as a Bonus Action, Argax gains temporary flight for 10 minutes or until he retracts the wings (no action required) or has the Incapacitated condition. During that time, he has a Fly Speed equal to his Speed.

Divine Sense. Argax can expend one use of his Channel Divinity to know the location of any Celestials, Fiends, and Undead within 60 ft., and know their creature types. In the same radius, he also detects the presence of any place/object that has been consecrated or desecrated, as with the Hallow spell. This lasts for 10 min.

Peerless Athlete. Argax can expend one use of his Channel Divinity to augment his  athleticism. For 1 hour, he has Advantage on Strength (Athletics) and Dexterity (Acrobatics) checks and the distance of his Long and High Jumps increases by 10 feet (this extra distance costs movement as normal).

Lay on Hands (35 HP). As a Bonus Action, Argax can touch a creature (including himself) and restore a number HP to that creature, up to the maximum amount remaining in the pool. He can also expend 5 HP from the pool to remove the Poisoned condition from the creature; those points don’t also restore HP to the creature.
