One of the main features to get new abilities in Lies of P is the P-Organ, a device in Hotel Krat that gives upgrades in complex node pathways that can be difficult to decipher. The vast array presented progresses naturally but costs valuable materials to unlock different sections. Those who understand the P-Organ can access even better improvements that help fight against the dangerous puppets that roam the city.
SCREENRANT VIDEO OF THE DAY SCROLL TO CONTINUE WITH CONTENT To even consider upgrading the P-Organ, you must first find special items called Quartz throughout the city. This material is incredibly rare, found only in secret areas and hidden locations scattered throughout the massive regions of Krat. Various bosses in Lies of P are also known to drop Quartz when defeated, so explore everywhere you can to find optional fights that may yield more of the item.
You must carefully choose which minor upgrades to apply to slots to unlock the node you want within a specific Phase. Only when two nodes have been completed, or four slots have been picked, will the P-Organ be improved to its next Phase section in Lies of P. Once you reach a new Phase, you will have to repeat the process to get to the next section, a pattern that repeats for the rest of the tree.
Thankfully, if you feel like you've made a mistake somewhere along the way within the P-Organ, you can reset all your upgrades and regain your spent Quartz. While doing this will cost Gold Coin Fruit in Lies of P, the chance to return with hindsight and re-assign improvements could make harder fights slightly easier. The Fruits needed for this reset spawn every 10 minutes from a tree found in Hotel Krat.
As you learn to upgrade the P-Organ, you should consider advantages that fit best with how you play, which may depend on what weapon Pinocchio wields or Legion Arm you have equipped. Eventually, these P-organ upgrades will enable you to face Lies of P's final boss with better buffs and skills.
