Pools of the Seers
Waytravel to the Pools of the Seers
As you arrive through the waypoint a stalactite immediately impedes your view. Everywhere you turn, the stone formation reach down from the ceiling obstructing your sight and your movement. You have to duck to proceed, and before long you find yourself striding through ankle deep waters emitting a pale luminescence. Discs of water reach out like terraced steps leading deeper and deeper into this claustrophobic cave, and you can make out that some lead down into water filled chambers impossible large for how close they are in proximity to one another. Who knows what wonders remain to be discovered in the Pools of the Seers?
Tier IV Waypoint | The Iron Coin will not allow anyone through of 16th level or lower.

Underwater Denizens
Creatures encountered within the Pools of the Seers have a swim speed of 30 feet if they do not possess a higher speed already, and the following abilities.
Amphibious. The creature can breathe air and water.
Bottom Treader. The creature takes no penalties to its movement or attacks underwater. It is immune to the effects of being underwater at a depth greater than 100 feet.
Aquasense. By sensing vibrations in the water, the creature possesses tremorsense out to a range of 100 feet while submerged. A creature with tremorsense can detect and pinpoint the origin of vibrations within a specific radius, provided that the creature and the source of the vibrations are in contact with the same ground or substance.
Above the surface of the water, while within the Pools of the Seers region, medium creatures can only move by squeezing and larger creatures cannot move at all. Below the water's surface, creatures of any size have enough room to move about unimpeded.
Natural Resources
Creatures inhabiting the Pools of the Seers are often mining Aquastone and may be carrying large amounts based on their size.

WANTED: Descended Dothreegesh Additional details regarding this Illithilich.
Prerequisites
- Spend five Lore to learn of Descended Dothreegesh and her activities within the Pools of the Seers
- Complete three difficult skill challenges, each involving one successful Stealth (Dexterity) check in order to reach Descended Dothreegesh's Hidden Sanctum unnoticed and slay her Flesh Golem Servant.
- Any creature entering the Hidden Sanctum triggers an Alarm spell which will alert the Illithilich to the intruder's presence. The Illithilich arrives three rounds later by way of Dimension Door, with an active Globe of Invulnerability, cast using her 8th level slot. Only by slaying the flesh golem before it acts, without entering the Hidden Sanctum can the Illithilich be Surprised.
Encounter Notes
Descended Dothreegesh keeps her phylactery in a fully enclosed chamber deep within the Pools of the Seers with a flesh golem servant. The servant utilizes a Scrying Orb to keep track of the location of The Astral Current and Grasping Maw, so that Descended Dothreegesh can avoid them. If the servant observes either creature being slain, it will convey this information to Descended Dothreegesh. Three rounds after either The Astral Current or Grasping Maw are defeated, Descended Dothreegesh arrives on the battlefield by way of Dimension Door, with an active Globe of Invulnerability, cast using her 8th level slot. She can be convinced not to attack immediately if a character acts before her in initiative and succeeds on a DC 25 Charisma check, and may add their proficiency bonus in Deception, Intimidation, or Persuasion. On a success, Descended Dothreegesh demands tribute in the form of a magical item of Rare rarity or higher, or a humanoid sacrifice with 12 Intelligence or more. Failure to offer either of these items before her next turn and any attempt to flee or attack her will result in her becoming hostile once more.Loot

WANTED: Grasping Maw Additional details regarding this Kraken.
Prerequisites
- Successfully complete three moderate skill challenges to activate the summoning horn. All three skill challenges must incorporate a successful Intelligence (History) check.
- Defeat a deadly encounter so that Grasping Maw smells blood in the water and comes out to feed.
Encounter Notes
Grasping Maw only ever attacks through the narrow water filled passages between the larger chambers of the Pools of the Seers. Until it has been bloodied (reduced to less than half of its starting health), it is considered to have three quarters cover against all attacks, as only its tentacles are visible and their thrashing movements make them much harder to hit. Spells and abilities which circumvent partial cover are able to effect Grasping Maw normally. If an effect would deal half damage to Grasping Maw on a successful Dexterity Saving Throw, Grasping Maw instead takes no damage and only takes half damage upon failing the Saving Throw until it has been bloodied. Three rounds after Grasping Maw is defeated, if Descended Dothreegesh has not been defeated in the last week, she arrives on the battlefield by way of Dimension Door, with an active Globe of Invulnerability, cast using her 8th level slot.Loot

Encounter Notes
