This is not my original idea, I got this from the WI forums and pretty much Im expanded from that. From the author of this, Leonim-If you are a Herbalist, you can make a trial account, invite yourself and (you cant NOT be saved in ulduar) go ulduar 10 and farm herbs underground, you will be hit by aoe so you need to heal yourself.
Each time you herbed the full room, you need to make a new char on the trial account, then you can go inside again and farmed it.
I just bought my Traveler's Tundra AND Signet of the Kirin Tor
PS: You can get at max 8 Frost Lotus each run and several other stacks
PPS: if you get KILLED (not pulled) by Freya, you will get saved, but it's easy to evade her underground
PPPS: as shaman, you can place totems under mobs so they aggro it while you take herbs under the mobs!
Ok I have screenies on how to do this
1.
Ulduar as normal, just as you entered it
2.
Fly high above the battlefield just cause the big dudes can still hit you
3.
Just above where XT should be in the scrapyard, No clip through the walls
4.
Just went pass the wall, you can now see the chambers, keep going north
5.
Where Kologarn should be, btw there is a hidden wall there so keep your noclip on
6.
This is Freya's room, now I forgot to take more screenies. Pretty much go underground and start herbing. Be careful of AoE and mobs tho
Good luck and have fun
