Notes & Tips
- There are multiple ways to reach Underdark. Either through the Defiled Temple, or jump from the phase spiders' tunnel using Feather Fall, use the Portal in Overgrown Tunnel, or use the elevator at Zhentarim Hideout.
You can shot the gem hold by Selune statue to disable the traps at front gate.
- Northwest to the Selunite fort, there's a rare sword Phalar Aluve, pass religion or strength checks to get it.
- The arcane tower is at the southwest of the Underdark, however, it's front gate is guarded by 2 arcane turrets. You can use Misty step or Feather Fall to climb the mushrooms on cliff near the arcane tower.
- To access the basement of the arcane tower jump down the gap of the wooden stairwell leading to the elevator.
- In order to Turn off the Arcane Turrets and activate the elevator, you need to reach the first floor of the Tower, and then combine Sussur Blossom with the generator. (You can find some at the backyard)
- Outside the Underdark fort, there are 2 minotaurs. One of them carries an uncommon amulet - Amulet of the Unworthy.
- Right next to the Underdark Fort, among a group of petrified Drows, there's a Spectator Beholder. After you killed the Spectator, if there's still some drow left (either freed by you or the beholder), they will attack you. However, if their leader - Dhourn was killed by either you (while he is mind controlled) or beholder, they'll stay neutral. Moreover you can find a Icy Helve on Dhourn's body (used for Mourning Frost), along with some info regarding Grymforge)
- On the top right corner of under dark, there's a storehouse full of valuable items.
- Near the Underdark - Sussur tree, there are 4 Hook Horror and a wizard.
- At the Underdark Beach, there is a group of dreugers waiting to ambush you. (Unless you use tadpole's psionic power or pass Deception/Persuasion 20 to talk your way out of this.) One of the dreuger has an uncommon 2 handed weapon - Exterminator's Axe. Cast the Speak with Dead spell and you can get some information from a dead raider.
- On one of the dead villager, there's an uncommon 1 handed weapon - Shortsword of First Blood.
- Blurg, the merchant at Myconid Colony, sells a rare Helmet - Circlet of Blasting.
