2) Spider fight. There are a few spiders here, which can be a pretty nasty fight if you get poisoned. Antitodes or cure/slow poison spells are a huge bonuse.

3) Outside the troll hut. There are trolls out front, as well as behind. However, the real challenge comes inside. When you zone into this hut, there will be two Trolls, a Spectral Troll, and a Spirit Troll. This can be a pretty rough fight, so it would be a good idea to rest before going inside. Any pets are a bonus, unless your party is pure melee, you probably don't have enough tanks to keep the trolls off of your weaker members.
After that battle, you are not done. There is still one Troll, and 3 giant trolls left in the back of the room. Using your thief, hiding, or invisibility, scout around and pull the remaining Troll solo. (Do this by having only the Troll in sight, as far from the Giant Trolls as possible) Setting traps with a thief in the middle of the room, out of sight of the Giant Trolls helps when you go to fight these buggers. You may consider going back outside and resting again before fighting the three Giant Trolls. I tried, but was never able to pull them one at a time.
After vanquishing all the foes, you can loot a couple of bone piles. Along with some gold, you find the Bracers of Archery and the Spear of the Unicorn.

4) Here you run into some druids fighting three trolls. You may want to watch, or only help slightly. If you jump in and down the trolls fast, the druids turn on you, and you have to fight them at near full strength. The spell caster can make this a tough fight.

5) Kyland Lind confronts you here with a group of Shadow Druids at his back. After a short dialouge, they attack. Spreading your force to have people in each druid's face, interupting spells is a good idea here. When Kyland gets low, he retreats. The Shadow Druids you have to fight to the death.

6) In this hut an old lady sells potions. However, when you work on the Tradesmeet Dao Djinn quest, you find out that this is actually a Rakasha. After taking the appropriate steps in Tradesmeet, she will morph into the Rakasha and summon two others. At this point in the game, this is a VERY hard fight. One you might consider putting off. (You will want to complete the rest of the druid grove quest first, at the least). Once you do defeat them, you are rewarded with the Periapt of Proof Against Poison and the Cleric's Staff +3. One thing worthy of note is that if you have Jan in your party, he will detect the Raksasha's illusion upon your first visit and you will not be able to buy any potions.
a) Inside this tower, hidden in a bail of hay, is a rather decent find, Belm +2

7) Myconids, two of them. Buff with atleast haste before they see you and start summoning other mushrooms to fight you. Unload everything you have on these fast. Killing them quick makes it an easy fight, but if you give them time to summon, this battle can quickly get out of hand.
a) Cernd, the druid you released from the Tradesmeet jail will meet you here, if you did not allow him to join you in Tradesmeet. If you still do not put him into your party here, you skip the outside battle at 8). I would suggest that you at least boot a party member temporarily here. There are a couple items at 8) that you might find worth the fight.
