Guild Wars 2

Right well most of us know that the three dragon chests give out atleast one rare per char pre day and the fire elemental, shadow behemoth, frozen maw and jungle wurm do to.
What i want to find out is what other events also guarantee a chest that gives a rare at the end.

just thought id see what other people have found out.
