Thunderbolt Iron Weapon (5e Equipment)
From D&D Wiki
Weapon (any), rare
When you hit an aberration or fey creature with this magic weapon, the creature takes an additional 2d6 lightning damage.
Planar Numbing. The first time an aberration or fey creature it hit an attack using this weapon, it must make a DC 13 Charisma saving throw. On a failed save, the creature has disadvantage on all ability checks and saving throws for 1 minute. On a successful save, the target is immune to the effects of this trait for 24 hours.
It is already uncommon to see a meteor from the farthest realms beyond stars strikes the earth, so it would be a surprise to see anyone wielding a weapon crafted out of the core of the alien ores.
Commonly known as "thunderbolt iron" for good reasons, this metal makes a curious reaction toward entities from Feywild, Shadowfell, or their distant cousins, as well as pseudonatural monstrosities touched by the Far Realm. The distinct gleam, reflecting and shifting light in a peculiar pattern that can only described as "eldritch", gives away its alien nature.
