Traits

Earth Armor. The bronze scout doesn't provoke opportunity attacks when it burrows.

Magic Resistance. The bronze scout has advantage on saving throws against spells and other magical effects.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit:5 (1d4 + 3) piercing damage plus 3 (1d6) lightning damage.

Lightning Flare (Recharges after a Short or Long Rest). Each creature in contact with the ground within 15 feet of the bronze scout must make a DC 13 Dexterity saving throw, taking 14 (4d6) lightning damage on a failed save, or half as much damage on a successful one.

Lore

The gnomes' efforts to invent and tinker with magic and mechanical devices produce many failed constructs, but also result in genuine advances, such as clockworks. Since their discovery, the methods used to craft clockworks have passed from one community of gnomes to another and down the generations.
