When they are killed, they always drop a ankheg shell, weighing 100 lbs, and some random loot of high quality.
They can appear in small groups of 2-5 or alone. Ankhegs can kill an entire low level party, or kill at least one member. Parties of level 3-4 can kill ankhegs, but only or two in a battle. Parties of level 5-6 can handle groups of 3-5 ankhegs at the same time.
Areas of appearanceEdit
Baldur's Gate IIEdit
They appear in the Windspear Hills area, but they can only be found alone. They no longer are such a threat to the party as they were in Baldur's Gate.
A nest of six corrupted ankhegs can be found to the East of the great tree by some glowing crystals at the bottom of Resurrection Gorge appear during Dorn Il-Khan's quest. (Enhanced Edition Only)
You need at least two warriors with a lot of hitpoints and good weapons & armor. They will fight the ankhegs in melee combat. The other group members use ranged attacks and it might be handy to have a lvl 5 mage who is able to cast Chromatic Orb, which can stun the target for three rounds. You also need someone who can take the shells. Minsc has a carrying capacity of 320 lbs or you can create a protagonist who can also carry a lot of weight. You can also obtain the Gauntlets of Ogre Power, they raise the Strength of the user to 18/00 and carriyng capacity of 400 lbs.
Command-Cleric Spell [level one] works very well if Charname and Party can deal sufficient damage quickly. Blindness-Arcane Spell [level one] works well and is longer lasting. Sleep-Arcane Spell [level one] works OK-@50% success rate. Note: best to delay half a turn before casting as the Ankheg wil be unaffected if it is underground when spell resolves.
Wand of Heavens [Cleric-Druid only] Wand of Frost [Mages and possibly Bards] Also Note: Wand of Sleep is useable by all classes.
Animate Dead or Monster Summoning can also help negate the deadly breath attacks. Also I have never tried Protection from Acid scroll but I have seen it recommended.
