Arcane Warrior: Spellblade

The spellblade, sometimes called the magus or the spellsword, is the most iconic of the arcane warrior classes. Often seen with a blade in one hand and a hand flickering with magic in the other, these duelists can dash across the battlefield, delivering strikes and spells in equal measure. Though they are primarily melee combatants, their spellcraft, mobility, and their ability to reflect spells back at their casters, makes the spellblade a terror at any range.

If the triggering attack was a melee attack and the attacker is within reach, you can make one melee weapon attack against them. If the triggering attack was a ranged attack, you can make a ranged spell attack against the attacker, deflecting their spell or projectile back at them on a hit, using your spell attack modifier.

If the melee weapon attack hits, the spell hits as well.
