Copper Citadel - no loot/ no Faridun Foray

Greetings,
It was the first time i've arrived to Copper Citadel and when the final boss died, ive died with him, so all the loot was gone. I was thinking, no problem, ill do it again, but i cannot redo it.

How should i get Faridun Foray now ?

Thx

do it again, when you find another one.
