Carian Knight

Magic Resistance. The Carian Knight has advantage on saving throws against spells and other magical effects. 

Perfect Defense. While wearing armor the Carian Knight adds one to its AC. 

War Wizard. The Carian Knight adds its intelligence modifier to its initiative rolls.

Multiattack. The Carian Knight makes two attacks with its sword and uses Carian Grandeur if available

Knightly Sword. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 15 (2d10 + 4) slashing damage plus 9 (2d8) force damage. 

Carian Grandeur (Recharge 5-6). The knight summons magical force and shapes it into a long, cleaving blade before slamming it down in a line that is 5 ft. wide and 30 ft. long. Any creature within that line must make a DC 18 Strength saving throw. On a failure the creature suffers 49 (10D8+5) force damage and is knocked prone. On a success a creature takes half as much damage only. 

Spellcasting. The Carian Knight casts one of the following spells, using Intelligence as the spellcasting ability (spell save DC 18):

At will: Mage Hand, Message, Dancing Lights, Prestidigitation

2/Long Rest Each: Detect Magic, Identify, Cloud of Daggers (at 3rd level), Magic Missile (at 4th level), Dispel Magic (at 4th level),

1/Long Rest: Sending,  Wall of Force

Carian Phalanx (2/Long Rest). The carian knight summons an arc of phantasmal swords above their head. These swords remain for one minute or until they are triggered which occurs when a hostile creature comes within 30 ft. of the knight. Upon being activated the swords lash out at the triggering creature and force it to make a DC 18 Dexterity saving throw. On a failure the creature takes 15 (3d8) force damage. On a success the creature takes half as much damage. 

Parry. The Carian Knight adds 5 to its AC against one melee attack that would hit it. To do so, the knight must see the attacker and be wielding a melee weapon.

Carian Retaliation (1/Long Rest). The knight interrupts a creature they can see within 60 feet of themself that is casting a spell. If the spell is 5th level or lower, it fails and has no effect. If the spell is 6th level or higher, the knight makes an Intelligence check (DC 10 plus the spell’s level). On a successful check, the spell fails and has no effect. Whatever the spell’s level, the caster takes 11 (2d10) force damage if the spell fails.
