Similar to Titanite in Soulslike, you need to have Moonstones to upgrade your weapons in Lies of P. Hidden Moonstone is the very first tier of these Upgrade Materials that can enhance to +3. You will also need some Ergo but that should not be an issue. Hidden Moonstones can be incredibly helpful during the early game since your damage is already very low. This guide will discuss all the different ways using which you should be able to farm a lot of Hidden Moonstones in Lies of P.
Lies of P Hidden Moonstones
Hidden Moonstones can be found scattered around the world. While you are roaming around, be sure to collect every shiny out there. This can be incredibly helpful during the early game when you do not have any other sources.
After you reach the St. Frangelico Cathedral, be sure to find an Elite with a shield on its arm. You need to defeat it to open a room with the Krat Supply Box inside. Once you have done that, hand it over to Polendina at the Krat Hotel. From that point forward, you will be able to purchase Hidden Moonstones from Polendina for 300 Ergo. This is probably the easiest way of getting Hidden Moonstones if you do not want to involve in any farming strats. Also, do not that Polendina gets an unlimited supply of Hidden Moonstones after the 4th chapter.
After completing the 8th chapter, enemies will start to drop Hidden Moonstones naturally. It is still a chance but if you want to save your Ergo for leveling, it does not hurt to farm a few enemies every now and then.
Lastly, do note that Hidden Moonstones can only upgrade a weapon to +3. After that, you will need to get Crescent Moonstones which is the next tier of Upgrade Material. These are even harder but if you are still in the early game, Hidden Moonstones are your primary concern.
This is everything we have on how to get unlimited Hidden Moonstones in Lies of P. If there is anything else that you would like to add, let us know in the comments down below!
