Excalibastard is stuck in a stone at Stanton's Liver. It is found by jumping across several cliffs at the left edge of the map, as seen from the entrance, before crossing the bridge leading to the refinery complex. After patch 1.02, it can be obtained from a Grinder.

Usage & Description
The Excalibastard is a versatile weapon for any character with Hyperion's reverse recoil effect and its guaranteed freeze chance on critical hits.
The Excalibastard works well with characters such as Wilhelm and Aurelia, who can invest in skills that increase laser effectiveness and cryo damage respectively. Athena can also make use of the guaranteed blade attachment and singularity effect on the weapon, which will provide melee-focused builds with a reliable source of freezing.
Excalibastard requires 2500 badasses to pick up. It may only be taken once per character, across playthrough modes.
Multiple cryo singularities can be created from one enemy as long as they survive the melee hits.
It is possible to freeze enemies as Nisha using Tombstone and grenades when the Excalibastard is held and the grenade scores a critical hit.
Jack's melee override, Merger, is treated as if the laser was shot from Excalibastard. As such, it is guaranteed to freeze enemies on a critical hit if he was using the weapon before executing the melee override.
The Excalibastard will scale itself to the Vault Hunter's level when removed from the stone. It is only limited by the level cap of the game mode it is obtained in.
The name is a portmanteau of Excalibur, the name of King Arthur's sword, and "bastard."
The Excalibastard is the only laser weapon that can spawn with a melee attachment.
