Inscryption

You will meet P03 when you enter the Temple of Technology and their snarky attitude may remind you of someone you meet in Act I...They will tell you to get their robot workers in line first before you can battle, so explore the Temple, opening chests and completing the same card puzzle games you have seen in Act I and in Leshy's cabin. 

As you gain card packs and open up pathways through the temple, you will find three robots that you will need to battle. Some of these pathways will require a new puzzle that deals with adding and subtracting energy. These are simple but a guide for the whole Temple, including all the math puzzles, is in the linked video below if needed. These puzzles and all of the battles you have in the Temple of Technology are designed to teach you how this playstyle works, and it would be good to learn how many of the technology cards work while you are here. 

Once you have battled the three bots, you can return to P03 for the boss battle. P03 uses a rotating conveyor belt that runs in a clockwise circle. This is important, because this means your cards will eventually be your opponents cards if they remain in play long enough to rotate to the middle row of slots. Try to focus on getting as many hits with low HP cards or cards that expire after use, like the Skeleton card. There is also a card called Gun Jimmy that shots all cards to the right of it, so that could be helpful if placed at the right time.

Once you complete the first round, P03 will scan your best card in play at that time and duplicate on their four slots before the belt is rotated, meaning at least one of that card will be on your side, but up to three of them will be against you. Fight off this trick play and tip the scale in your favor to win the battle and complete the Temple.
