It works exactly like the one in PGR: you choose the difficulty, boss buffs, and personal buffs/debuffs. There might also be environmental effects (for example: perform certain requirements to damage the boss).
On the right, there's a "score" that reflects the difficulty level, the higher it is, the harder it is. In PGR, it was used to flex skills, probably also in Wuwa with the leaked badges from yesterday.
