Persona 5 The Phantom X: How to Allocate Stamina
For levels 1-40, we only need to follow the order of unlocking masks > Phantom Potential (Character breakthrough) > Weapon breakthrough > Skill upgrade.

The difference in skill upgrades between levels 30 and 40 is only around 100 Soul Stones (money). In non-stuck situations, upgrading skills appropriately is sufficient.
There is not much difference in the training sequence from 40-50 compared to before. It is important to note that after level 35, you do not need to grind for Revelations. The main ways to obtain Revelations currently are through Owl Targets, Palaces, and Treasure Chests in the Impression Space.

It is recommended to strengthen low-star Revelations related to life and attack power for clearing, as well as the invincible Gana Jun.
Due to the Owl Shop, we need to train 8 level 50 characters and weapons. First complete the upgrade of the first team for clearing, then focus on attribute characters used for strategies.
To upgrade skills from 6 to 7, you need 3 gold materials and the difficult-to-obtain Enchanting Fragrance for enhancement.
Therefore, if you have not reached level 50 after completing the above goals, it is recommended to use stamina to upgrade the skills of common characters to level 6 to improve scores. If you can reach level 50 before the update of the Heart of the Sea and Guild War, it is recommended to grind for character and weapon breakthrough materials.
At level 50, gold Revelations officially drop from Gold Revelations Books, and the drop rate of Gold Masks becomes 0-1. After obtaining the necessary Purple Masks, it is recommended to grind for at least two sets of Strength Revelations (for general output sets, used for clearing with two C or two teams respectively, except for Li Yaoling’s speed, other main attributes should be output-oriented).
Since the difficulty of Revelations Books is not high, you can upgrade characters and weapons after obtaining two sets of Strength Revelations. If you cannot defeat the Revelations Books or need to increase points, it is recommended to focus on breakthroughs first.
Stable dropping of gold materials for skill upgrades is not guaranteed, so it is not recommended to grind during this stage.
Finally, in order to break through characters and weapons to level 70, you will need 12 gold materials. By then, the priority between them depends on whether the resources can be obtained stably from the corresponding books.
