In Lies of P, maximizing the potential of special weapons requires extremely rare upgrade components known as Full Moonstones of the Covenant. Unlike standard equipment that utilizes regular moonstones, special weapons obtained from boss Ergo demand these specialized materials to reach their highest potential. Knowing where to locate these scarce items ensures that your favorite boss gear performs effectively during late-game encounters.
Understanding the Purpose of Full Moonstones of the Covenant
Full Moonstones of the Covenant serve as the final refinement material for boss weapons in Lies of P. Upgrading a special weapon from level +3 to +4 requires one Full Moonstone of the Covenant, while upgrading from +4 to its maximum level of +5 requires two. Because their overall supply is limited within a single playthrough, players must carefully choose which weapons to prioritize.
These enhancements are performed exclusively at Eugenie's workbench located on the ground floor of Hotel Krat. Investing these resources into a preferred weapon significantly boosts its physical attack power and scaling capabilities. Careful planning guarantees that your limited supply provides the highest return during challenging boss fights.
Key Locations to Find Full Moonstones of the Covenant
Several Full Moonstones of the Covenant are scattered throughout the final chapters of the game, particularly around Arche Abbey and the Relic of Trismegistus. In the Relic of Trismegistus Entrance area, defeating a specific Dimensional Butterfly near a bonfire rewards players with one stone. Another Dimensional Butterfly carrying this rare item can be found near the Stargazer in the Arche Abbey Outer Wall area.
Exploration within Arche Abbey reveals additional stones hidden on elevated platforms and upper walkways. Players can discover one on a metal platform in the Arche Abbey Upper Part and another near wooden planks in the upper levels. Additionally, an elevator at the Ascension Bridge holds a stone, while a safe inside the Trinity Sanctum at Krat Central Station Lobby contains one during New Game Plus runs.
Unlocking Full Moonstones of the Covenant via Merchants
Players can also purchase a Full Moonstone of the Covenant directly from Polendina at Hotel Krat. To expand Polendina's shop inventory to include this item, players must find and hand over all three Krat Supply Boxes hidden throughout Krat. The final box, known as the Special Krat Supply Box, is located on a cliff overlooking the Collapsed Street zone.
Once all three boxes are delivered, Polendina stocks a single Full Moonstone of the Covenant alongside other rare materials. Checking his shop regularly ensures that you do not miss out on vital crafting resources before entering the final boss arenas. Combining merchant purchases with field exploration grants enough materials to fully upgrade a couple of special weapons per playthrough.
Strategies for Managing Upgrade Materials Wisely
Due to the relative scarcity of Full Moonstones of the Covenant, spreading them across multiple boss weapons early on is generally discouraged. Focus on testing a weapon's moveset at level +3 before committing your ultimate upgrade materials. If a weapon's playstyle does not suit your combat preferences, save your stones for alternatives unlocked later in the campaign.
Entering New Game Plus provides another opportunity to gather these materials from the same fixed locations and chests. This allows dedicated players to eventually max out additional special weapons across successive runs. By balancing careful exploration with smart resource management, you can maintain a top-tier arsenal ready for any threat.
