Tempest Trials+ are limited-time events where you battle through a series of maps with increasing difficulty. Your score accumulates over multiple runs, earning you rewards like Orbs, Hero Feathers, Sacred Seals, and exclusive heroes. Using bonus units (featured heroes from the current banner or specific older heroes) grants significant score multipliers. Stamina potions are often used here to maximize runs. It's a great way to quickly level up new units and acquire valuable resources.
