Lies of P challenges players with intense combat against formidable bosses, rewarding them with Rare Ergo upon victory. These special items serve a crucial purpose beyond simple upgrades: they can be exchanged for exclusive boss weapons or potent amulets. This guide explores the mechanics of acquisition, strategic choices, and in-depth breakdowns of each option to help you conquer the twisted streets of Krat.
Unlocking the Boss Ergo Trading System
The path to boss weapons and amulets begins with encountering Alidoro, the wandering treasure hunter. He appears first in St. Frangelico Cathedral, specifically at the Library Stargazer. From there, navigate through zombie-infested corridors, ascend stairs to dispatch a noxious enemy, and proceed to a flooded chamber with an altar. Continue to a book-lined room where Alidoro awaits, seeking shelter. Direct him to Hotel Krat for the optimal outcome, enabling trades post-Fallen Archbishop Andreus defeat.
After this boss, Alidoro relocates to Hotel Krat, positioned near familiar NPCs. Here, spend your Rare Ergo on either a unique weapon mimicking the boss’s arsenal or an amulet granting specialized buffs. Note that each major boss drops one Rare Ergo, forcing a pivotal decision: prioritize offensive power or defensive utility? Alidoro’s location shifts later—post-Champion Victor, he moves to Barren Swamp, and eventually to other spots like Relic of Trismegistus.
Strategic Decisions: Weapons vs. Amulets
Every trade pits a boss weapon against an amulet. Weapons are non-disassemblable, featuring bespoke Fable Arts that echo the boss’s moveset, ideal for collectors or specific builds. Amulets, conversely, offer passive enhancements like stamina tweaks or damage boosts, stacking with your arsenal for versatile progression.
- Weapons excel in: High-damage Fable Arts, unique designs, and build synergy (Motivity, Technique, or hybrid).
- Amulets shine for: Survivability, resource efficiency, and Legion Arm improvements.
Early-game temptation to consume Ergo for levels is strong, but saving them unlocks game-changing gear. Specters summoned during these fights wield the corresponding weapon, previewing its potential.
