Class Breakdown: Artificer 5 (Artillerist)/ Fighter 1

Burnice White is the fire-loving free-spirited bartender of The Sons of Calydon. This build is of her keeping her foes nice and toasty with her firebug tendencies.

Artificer is the main class for Burnice, giving her access to her trademark shades and the ability to craft equipment and weapons that burn her enemies with fire’s radiant embrace. With Artificer she gains the proficiencies of Investigation, Sleight of Hand and Alchemist’s Supplies, Magical Tinkering, Spellcasting, Infuse Item, Artificer Infusions of Enhanced Weapon, Mind Sharpener, Replicate Magic Item: Googles of Night, and Repeating Shot and The Right Tool for the Job.

Artificer Specialist: Artillerist is where Burnice gains the power necessary to blaze her foes’ bodies with the warmth of her fiery charms. Artillerist gives her Tool Proficiency of Woodcarver’s Tools, Artillerist Spells of Shield, Thunderwave, Scorching Ray and Shatter, Eldritch Cannon: Flamethrower and Arcane Firearm.

Fighter is where Burnice picks up a potent unarmed attack as well as a self-heal. Fighter gives her heavy armor and martial weapon proficiencies, and her fighting style is unarmed fighting and second wind.

The feat Strike of the Giants: Fire Strike gives her an extra 1d10 fire damage when she lands either a melee weapon attack or a range attack attack using a thrown weapon.

The feat Ember of the Fire Giant (Con) gives her a +1 to her Con, fire resistance, and the ability to replace an attack with a magical burst of fire in a 15-foot radius centered on her that can damage and blind a foe with fire damage.

The feat Elemental Adept (Fire) allows her to ignore the fire resistance of foes when she cast spells as well as the ability to treat any fire damage from her spell that lands as 1 to be treated as 2.

Background: Giant Foundling gives Burnice White the proficiencies of Intimidation and Survival, the Languages of Giant and Elvish, and the Background Feature of Strike of the Giants.
