Artillerist

Spellcasting. The artillerist is a 3rd-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 13, +6 to hit with spell attacks). The artillerist has the following artificer spells prepared:

Cantrips (at will): fire bolt, shocking grasp

1st Level (3 slots): expeditious retreat, faerie fire, false life, feather fall, shield, thunderwave

Infusions. The artillerist has two items infused with magical properties: its chain shirt which provides a +1 bonus to its armor class (included), and its spellcasting focus which provides a +1 bonus to its spell attack rolls (included). If the artillerist dies, these magical properties end 3 days later.

Multiattack. The artillerist uses its Eldritch Cannon and casts a spell with a casting time of one action.

Eldritch Cannon. The artillerist's handheld cannon magically exhales fire in a 15-foot cone originating from the artillerist. Each creature within must make a DC 13 Dexterity saving throw, taking 9 (2d8) fire damage on a failure or half as much on a success.

Fire Bolt (Cantrip). Ranged Spell Attack: +6 to hit, range 120 ft., one target. Hit: 5 (1d10) fire damage.

Shocking Grasp (Cantrip). Melee Spell Attack: +6 to hit, reach 5 ft., one creature. Hit: 4 (1d8) lightning damage and the target can't take reactions until the start of its next turn. This attack has advantage if the target is wearing armor made of metal.
