No, there isn't, but one would not be a bad idea (anyone care to submit one?).
Without such a guide, your best bet is to get some paper or open a spreadsheet, write down each spawn site, its essence type, and the creatures that occur at that spawn. Then, look up those creatures on Stratics or a similar site, see what their weaknesses and special attacks are, and make your decision from that information.
One example can be the spawns with the Fire Daemons, Fire ants, etc..
These spawns have both area effect attacks and ranged attacks you can't really avoid, so you'd want to have the ability to either regen through them, or stay where you only get hit at range, while your pets or summons take the brunt of the damage. You'll also need to hide (or cast invisibility) a LOT to break targeting on you by aggressives. Provocation is also good, both to get the creatures attacking each other (not you) and for the Mastery powers (one of which regens you, your pets and your summons every 4 seconds, plus gives stat boosts). The one between the goblins and Fae spawn on the West side of the abyss gives the better essence of the two, but is considerably more constricted in its terrain. Ironically, the renowneds are easier than the basic spawn is as a whole, provided the spawn is reduced down before you turn your attention to them.
You're on your own, for researching the rest.
