Requirements and conditions
- Contribution is capped damage divided by boss maximum HP, floored to a whole percent. Below 15%, the handler grants ashes and junk and stops before unique, clue and pet checks.
- The main checks are ordered: unique, dossier, lockbox, shards, then standard fallback. A later check is conditional on earlier misses.
- Custom ethereal essence and shiny Yami are explicitly enabled by the live Aleges reward call.
How rewards are calculated
- Rewards are delivered through the encounter’s normal ground-drop path after victory. The player must still be a current participant when rewards settle.
- The Forgotten lockbox can then be opened in the inventory; its opening pool has its own acquisition page.
A reward-pool weight is its share within that pool, not your overall chance per completion. Eligibility, pool selection and the listed modifiers still apply.
