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.
- This contract does not enforce the solo-only flag.
- Only the presenting owner receives its guaranteed settlement. Familiar-contract backing has separate eligibility for unrelated Ironman participants.
How rewards are calculated
- The ordinary unique/dossier/lockbox/shard checks and standard fallback pool remain available.
- Familiar acquisition changes the pet denominator for its eligible participants; a pet remains a roll rather than a guaranteed settlement.
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.
