The supplied video description says you can attempt Purgatory difficulty in Sword x Staff after reaching 28.5M power. Reach that milestone before trying the difficulty.
The description does not specify whether 28.5M is a strict entry requirement or a recommended threshold. It also does not provide build, gear, or combat advice, so it cannot establish what preparation Purgatory requires.

Good guide for Sword x Staff players. The strategy part was useful.
This saved me time in the early game.
Nice guide. I am checking the other Sword x Staff articles next.
The explanation is clear, especially for beginners.
