From D&D Wiki
Weapon (Longsword), legendary (requires attunement)
Kiaroaro's Predicament has a blade forged from dragonsteel made with the scales of a copper dragon. A kyber shard pommel contains the essence of Kiaroaro the copper dragon. A wizard friend pranked her and accidentally trapped her inside the shard.
You have a +3 bonus to attack and damage rolls made with this magic weapon.
Copper Dragonsteel. This weapon deals an additional 2d10 acid damage.
Kiaroaro's Grip. Copper dragons are powerful jumpers and climbers, with massive thigh and shoulder muscles. While attuned to this sword, the wielder is permanently under the effects of a spider climb spell.
Dragon Breath. 3 times a day while holding the blade you may breathe acid in a 90-foot line that is 10 feet wide. Each creature in that line must make a DC 16 Dexterity saving throw, taking 7d8 acid damage on a failed save, or half as much damage on a successful one.
