No doubt many people are getting into there 20s now, and started to think about doing access quests, one thats proberly been hinted at is the Enchanted Lands (Misty Thicket) since thats where a lot of Tier 4 harvest goodies are, and a ton of nice mobs to hunt, however getting there isn't as easy as some guides claim and I think the reason is in a recent update the final mob has been beefed up, come guides say this for the final encounter.
"The first three waves are level 27 foulmists. The next three waves are level 28 nightwretches. The final wave is a Group x 2 boss (Lord Zaavan) and his henchman. Even though the boss is tagged as a Group x 2 mob, you can defeat him with a single group of level 25 characters. Expect a very tough fight, however. This is not a trivial encounter by no means."
We attempted the crossing with this set-up of a group.
lv 27 Shammy
lv 27 Ranger
lv 26 Templar
lv 26 Berserker
lv 25 Wizard
lv 25 Conjuror
Fully buffed up, warded and full with Refreshing Whisky regen drink, the normal encounters was not a problem at all, very laggy as they at least 8 in each group, we got to the Lord himself, conned orange ^^x2 to me at lv 27, we tried it and failed badly and was forced to evac. He hits for at least 500+ and has around 300+dmg AoEs, the shammys ward was no way near powerful enough to stop any of the damage done, we did manage to take him down to about half HP before calling it a day, but we did manage to get some ideas on how it could be done.
First off, I think this quest should be raised to at least lv 30, 25 is enough to do Part 1 and Part 2 without problems but the final part isn just not enough, if the whole group was around lv 30 and had a mezzer in the group, I think it would definately be possible to take him, still wouldn't be easy but I'd bet my money on the group could do it.
Good Luck!
