Mercenary Mage (5e Creature)
From D&D Wiki
Medium humanoid (any race), any alignment
Multiattack. The mage makes one attack with its rapier and casts a cantrip.
Rapier. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) piercing damage.
Mercenary mages blend wizardry and battle cunning to make themselves rich on the battlefield. Their magic can burn soldiers to the bone, paralyze leaders, and empower allies—making their services far more valuable than those of a common sellsword. Wealthy nobles or adventurers may even hire one as a personal escort.
