Ok guys, nice job on the build and the method of farming, very nice work, I don't post very often but I love farming out of the way areas and have been farming the forest for sometime now. The build I am posting is nothing new or even very exciting, but it gets the job done very well...
sprint
elemental resistance
VIM (elite)
Heal Sig
Doly Sig
Sever Artery (VIM and bleeding

)
Gash (again VIM and deep wound)
and this one is up to you, I use Final Thrust but do change sometimes for fun
No big secret here, I run full glads with knights boots with sup strength and sup swords, major absorption, major vigor and minor tactics although sup tactics can also be used. I am at work so I can't name my attributes exactly but I run doly sig at 20 secs., so no gap, ele res is at 50 secs and I believe VIM heals me for 53 hps per condition, the rest in swords. Now my sword is zealous and it has an armor +7 vs Physical and I use the crimson carapace shield of course, the only tough mob in the forest are the spirit wood or w/e they are called, so run doly and ele res at all times while fighting these, to me they do 12 lightning damage (thats right 12) and only 24 when chain lightning, so when fighting 3 I use heal sig usually only once and VIM until I have killed 1, then usually VIM is more than enough, I have 360 hps before the shield mod, if they are wanding me, I take 0 damage and will actually regen naturally, for every other mob, doly is fine except for the rock borer things, you can just kill them easy without doly if you choose, anyways, I never die doing this run but do enjoy the somewhat challenge...hope it helps...also, as you can see, you don't need high end gear for this and plate is not necessary...enjoy
