ACTIONS
Multiattack. The arcane blademaster attacks four times and casts a cantrip.
Longsword. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 11 (1d8 + 7) slashing damage.
Composite Longbow. Ranged Weapon Attack: +11 to hit, range 150/600 ft., one target. Hit: 9 (1d8 + 5) piercing damage.
Shocking Grasp (Cantrip; V, S). Melee Spell Attack: +11 to hit, reach 5 ft., one creature. Hit: 18 (4d8) lightning damage, and the target can’t take reactions until the start of its next turn.
Fire Bolt (Cantrip; V, S). Ranged Spell Attack: +11 to hit, range 120 ft., one target. Hit: 22 (4d10) fire damage.
Globe of Invulnerability (6th-Level; V, S, M, Concentration). A glimmering 10-foot-radius sphere appears around the blademaster. It remains for 1 minute and doesn’t move with the blademaster. Any 5th-level or lower spell cast from outside the sphere can’t affect anything inside the sphere, even if cast with a higher level spell slot. Targeting something inside the sphere or including the sphere’s space in an area has no effect on anything inside.
Teleport (7th-Level; V). The blademaster teleports to a location they are familiar with on the same plane of existence.
Unholy Star (7th-Level; V, S). A meteor explodes at a point the blademaster can see 100 feet directly above them. Each creature within 120 feet that can see the meteor (other than the blademaster) makes a DC 19 Dexterity saving throw . On a failure, it is blinded until the end of the blademaster’s next turn. Four fiery chunks of the meteor then plummet to the ground at different points chosen by the blademaster that are within range, to explode in 5-foot-radius areas. Each creature in an area makes a DC 19 Dexterity saving throw, taking 21 (6d6) fire damage and 21 (6d6) necrotic damage on a failed save or half damage on a successful one. A creature in more than one area is affected only once. Flammable unattended objects catch fire.
Power Word Stun (8th-Level; V). The blademaster utters a powerful word that stuns one creature that has 150 hit points or less and is within 60 feet (if it has more hit points, it is instead rattled until the end of its next turn). The creature repeats the saving throw at the end of each of its turns, ending the effect on a success.
Meteor Swarm (9th-Level; V, S). Scorching 40-foot-radius spheres of flame strike the ground at 4 different points chosen by the blademaster within 1 mile. The effects of a sphere reach around corners. Creatures and objects in the area make a DC 19 Dexterity saving throw , taking 49 (14d6) fire damage and 49 (14d6) bludgeoning damage on a failure or half damage on a success. A creature in more than one area is affected only once. Flammable unattended objects catch fire.
BONUS ACTIONS
Improved War Magic. When the blademaster uses an action to cast a spell, they can make one weapon attack.
Misty Step (2nd-Level; V). The blademaster teleports to an unoccupied space they can see within 30 feet. The blademaster can’t cast this spell and a 1st-level or higher spell on the same turn.

Humanoids include a number of different intelligent, language-using bipeds of Small or Medium size. Humans and elves are humanoids, and so are orcs and goblins. Humanoids may employ magic but are not fundamentally magical—a characteristic that distinguishes them from bipedal, language-using fey, fiends, and other monsters. Humanoids have no inherent alignment, meaning that no humanoid ancestry is naturally good or evil, lawful or chaotic.
