In Lies of P, maxing out your special weapons requires rare upgrade materials known as Full Moonstones of the Covenant. Finding these items allows players to maximize weapon scaling and damage output right before facing the game's toughest late-game encounters. Knowing exact pickup spots and vendor options ensures you do not miss these valuable assets during your playthrough.

Key Functions of Full Moonstone of the Covenant

Full Moonstones of the Covenant serve as the ultimate upgrade tier specifically dedicated to boss weapons and special armaments. Taking a weapon from level +4 to its cap of +5 significantly boosts offensive stats and weapon efficiency. Because these stones are scarce, deciding which special weapon to fully upgrade requires careful consideration.

Dimensional Butterfly Locations and World Drops

Several Full Moonstones of the Covenant drop directly from Dimensional Butterflies in end-game zones. You can hunt one near the bonfire by the Relic of Trismegistus Entrance Stargazer, as well as along the ledges in Arche Abbey. Additional pickups rest inside elevators at Ascension Bridge and within safes in New Game Plus Trinity Sanctums.

Vendor Unlocks and Hotel Krat Shop Options

Players do not have to rely solely on exploring treacherous platforms to acquire these upgrading materials. By handing over all required Krat Supply Boxes to Polendina at Hotel Krat, the vendor expands his inventory to sell a Full Moonstone of the Covenant. Purchasing this item provides a reliable shortcut to powering up your favorite gear.

Strategic Tips for Weapon Upgrades

Prioritize upgrading special weapons that align best with your character's primary stat build, such as Motivity or Technique. Since resources are limited in a single run, focus on finishing one main weapon before investing in secondary options. Entering New Game Plus unlocks additional safes and rewards, allowing you to eventually max out multiple special weapons.
