Cornelius Nettle, Lord of Nettleholm

Aura of Warding. Ancient magic surrounds Cornelius. Creatures of his choice within 10 feet have Advantage on saving throws against spells.
"The old groves still remember their promises."

Noble Bearing. Creatures friendly toward the Crown or House Nettle instinctively trust Cornelius. He has Advantage on Persuasion checks involving matters of duty, loyalty, and peacekeeping.

Lay on Hands (3/Day). Cornelius restores 15 hit points to a creature he touches.
"Stay with us."

Multiattack. Cornelius can make 2 attacks with Grovesbane, 1 Ancient Rebuke, or cast a spell.

Grovesbane. Legendary Longsword from one of the five noble Cormyrian houses. Melee Attack Roll: +7, reach 5 ft. Hit: 10 (1d10 + 6) Slashing damage plus 4 (1d8) Radiant damage. Against fiends, undead, and creatures that have damaged one of Cornelius's allies since his last turn, Grovesbane deals an additional 4 (1d8) radiant damage. The blade bears engravings of ancient vines climbing toward a rising sun.
"The Nettle line protects its own."

Ancient Rebuke (Recharge 5–6). Roots burst from the earth beneath a creature within 60 feet. The target must succeed on a DC 15 Strength saving throw. On a failure target takes 18 (4d8) radiant damage and is restrained until the end of its next turn. On a success target takes half damage.
"You have forgotten your place in the natural order."

Spellcasting. Lord Cornelius can casts one of the following spells, using Charisma as the spellcasting ability (spell save DC 15):

At Will: Light, Sacred Flame, Druidcraft

2/Day Each: Command, Cure Wounds, Shield of Faith

1/Day Each: Aid, Daylight

Nettleholm Rally (1/Day). One ally within 30 feet gains 10 Temporary Hit Points and advantage on their next saving throw.
"Stand. We're not finished yet."

Divine Smite (3/Day). When Cornelius hits with Grovesbane, he may deal an additional:
13 (3d8) radiant damage.
"Enough."

Protect the Hearth. When an ally within 10 feet takes damage, Cornelius may move up to 10 feet toward them without provoking Opportunity Attacks.
"Family first."

Guardian of the Household. When a creature within 5 feet of Cornelius is hit by an attack, he may interpose Grovesbane. Cornelius reduces the damage by 11 (2d10). If the damage is reduced to 0, Cornelius may immediately make one attack against the attacker.
"You'll go through me first."

Legacy of Nettleholm (1/Day). Cornelius calls upon the accumulated oaths of generations of House Nettle. For 1 minute:

• Allies within 15 feet gain 5 Temporary Hit Points at the start of their turns
• Difficult terrain does not affect allies
• Grovesbane deals an additional 7 (2d6) radiant damage

Additionally, whenever an ally within the aura would be reduced to 0 hit points, they instead drop to 1 hit point. This effect can occur once per creature as spectral green-gold branches rise around the battlefield, forming the silhouette of an ancient forest.
"A lord does not stand above his people. He stands with them."
