Which epics are MQable sub lvl 46?

[Ravun]

Apologies if this has been asked before, but I wasn't able to find a thread that answered this specific question:

I understand there are some epics are are available at lvl 1 like rogue, cleric, monk, etc. I also understand from my own experience that the paladin epic turn-in requires lvl 46+ to enter the planes. Could someone please tell me a list of which epics are able to be completed/MQed sub 46? If a class's epic requires 46+ could you give me a very brief explanation as to why? I am mainly interested if either of the ranger epics are MQable at lvl 1, but I'm also curious about others.
