Clan Boss chest rewards

Clan > Demon Lord Clan Boss.

Before you go

Open the Clan Boss screen and review available Demon Lord difficulties.
Ask or check which difficulty your clan is currently defeating and which chest tier your team can reach.
Choose the highest suitable difficulty where your roster can deal reliable damage.
Spend an available key and complete the battle; use the result to assess team damage.
Use further keys according to the clan’s progression and your damage capacity.
After the clan defeats the boss, collect the available chest reward.
Review the drops and apply useful resources to Champion development or gear progression.

Damage dealt affects Clan Boss rewards, so a difficulty your team can meaningfully damage may be more useful than an unproductive higher one.
A clan that defeats the boss can provide a second chest according to the recorded beginner guidance; confirm the current result in game.

Repeat while keys are available. Chest rewards depend on battle damage and whether the clan defeats the boss; key supply limits each cycle.

Joining a clan that rarely defeats the boss when chest access is the goal; check activity expectations first.
Choosing a difficulty your team cannot damage effectively; use battle results to select a workable tier.
Expecting a fixed chest item; collect and evaluate the actual reward.

Use all keys you intend to spend for the current cycle, then switch to roster building or another Clan activity until keys are available again.
