Sword of Power - Excalibur (5e Equipment)
From D&D Wiki
Weapon (shortsword), legendary (requires attunement)
Excalibur is one of the four Swords of Power, and like them, it is a stone shortsword with power over a specific element, Excaliburs' being water and ice. The only difference between the four swords is their hilts, and looks ashy grey.
This weapon has a +1 bonus to attack and damage rolls, and on a hit deals an additional 2d6 bludgeoning damage. This weapon also grants its wielder resistance to bludgeoning damage.
Sword of Frost. When a target's current HP is in single digits or 10% or lower of their maximum amount, and you make a successful attack towards them, the target turns to ice, unless they are immune to bludgeoning damage.
The Melding of Power. If you choose, you can meld two or more swords, which belong in the Sword of Power set, together, costing one action for two and two actions for three. Melding four costs a short or long rest and creates the Hook of Aether. A melded sword stacks all of their magical properties and stats, but not normal shortsword damage (i.e. a melded sword does a base 1d6 piercing plus +1 bonus to attack and damage rolls and 2d6 fire/lightning/bludgeoning damage equal to the number of swords melded).
