Mjölnir

The Mjölnir is a unique and powerful Hardmode, post-Moon Lord true damage weapon that is only obtainable in Expert Mode after defeating The Primordials. It rapidly throws returning images of the legendary hammer that can pierce enemies infinitely. The first hit of every throw will create a lightning chain that strikes up to 10 additional nearby enemies. When right-clicked instead, the hammer generates a shield of electricity that creates its own lightning chain when damaging enemies. The shield must recharge for 3 seconds afterwards before it can damage enemies again.

Note that it has no specific class, as it deals true damage rather than melee, ranged, magic, summon, throwing, radiant, or symphonic damage. This also means that its damage value is not affected by any other damage modifications. It also cannot receive modifiers.
