Captain Gideon, Herald of Magic

Legendary Resistance (3/Day). If Gideon fails a saving throw, he can choose to succeed instead.

Magitech Mastery. Captain Gideon is a unique blend of archaic magic and modern technology. He can seamlessly integrate technological items with his spellcasting abilities. When casting a spell and using a technological weapon (such as his Antimatter Rifle), he may make an attack as part of the same action.

Innate Spellcasting. Captain Gideon's innate spellcasting ability is Charisma (spell save DC 22, +14 to hit with spell attacks). He can cast the following spells innately, requiring no material components:

At will: detect magic, mage hand, counterspell

3/day: shield, dimension door, greater invisibility

1/day: time stop, disintegrate

Surge of Magic. Captain Gideon can reroll a failed spell attack, saving throw, or technological weapon attack. He must use the second result and can use this ability only once per long rest.

Multiattack. Captain Gideon makes three attacks: two with his Antimatter Rifle and one with a spell.

Antimatter Rifle. Ranged Weapon Attack: +13 to hit, range 150/600 ft., one target. Hit: 45 (9d8) force damage. On a critical hit, the target suffers an additional 27 (5d10) force damage.

Arcane Burst. Ranged Spell Attack: +14 to hit, range 120 ft., one target. Hit: 32 (6d6+8) force damage and the target must succeed on a DC 22 Dexterity saving throw or be knocked 30 feet back and fall prone.

Arcane Disruption Field (Recharge 5-6). Captain Gideon releases an arcane pulse that destabilizes magic around him in a 30-foot radius. Any creature within the area must succeed on a DC 22 Intelligence saving throw or be unable to cast spells or use magical abilities until the end of their next turn. Magical effects, such as spells or magic items, cease to function in the area until the start of his next turn.

Phase Step. As a bonus action, Captain Gideon teleports up to 60 feet to an unoccupied space he can see. After teleporting, he gains advantage on his next attack roll before the end of his turn.

Captain Gideon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Gideon regains spent legendary actions at the start of his turn.

Detect. Captain Gideon makes a Wisdom (Perception) check to detect hidden or invisible creatures.

Technomagic Surge. Captain Gideon alters the flow of magic and technology, allowing him to regain a use of either his 'Phase Step' or 'Arcane Disruption Field' abilities.

Antimatter Barrage (Costs 2 Actions). Captain Gideon fires a barrage from his Antimatter Rifle at up to three targets within range. Each target must succeed in a DC 22 Dexterity saving throw or take 45 (9d8) force damage.
