If any of the boss weapons in exchange for the Rare Ergo of its defeated boss doesn't take your fancy, you can also trade each Ergo for a particular amulet instead - each with their own powerful effect when equipped. 

For example, instead of exchanging the King's Flame Ergo (the reward for beating the King’s Flame Fuoco boss) for Holy Sword of the Ark, you can trade it for the Conquering Amulet instead.

All boss amulets you'll be able to exchange for after beating each boss in Lies of P are as follows:

How to exchange boss weapons in Lies of P

To exchange boss weapons in Lies of P, you need to speak Alidoro, who you will first find in the St. Frangelico Cathedral Library, the game's fourth area, by taking the lift to the upper outdoor terrace.

Once you’ve spoken to him and told him about the safe space in Hotel Krat, he will head there and you can speak to him in the lobby of the hotel near Antonia. Alternatively, you can lie and tell him about Venigni Works instead - where you can later find him by the Workshop Union Entrance stargazer

As demonstrated above, each unique Rare Ergo dropped by the boss gives you two options to choose from, but you can only pick one. If you miss out on a reward, you can get it again in New Game Plus. Boss weapons cannot be disassembled, so you can only use them as they are and use the skills they come with. Keep this in mind when you are making your choice.

That’s everything you need to know about boss weapons in Lies of P.
