@User:Khallyl Please use the edit button next time.

once you defeat a boss in a free quest stage, they usually drop. if this kind of chest included a rainbow like so, its a confirmed event CE

but do note in other events there will be more than 1 event CE in a free quest node and a alternate drop next to the chest which is like a star icon.
