Other Useful Items
Ayleid Cleansing Shrine
The Ayleid Cleansing Shrine is in Pratal's Coffer in the room from which Lord Pratal emerged from in the the Lost Ruin Substructure in the quest
The Elven Hero.
The Cleansing Shrine works in the same manner as the altars of the Nine Divines. If your Fame is greater than your Infamy, once per week the Cleansing Shrine can be used to cure disease.
Haunted Lamp
The Haunted Lamp is possessed by the lich, The Soothsayer, found in Hidden Passage in the quest
The Revelation. The Soothsayer also posseses the Lamp's ability.
The ability gained from the Lamp depends on the player's Conjuration level.
If Conjuration is under 50, you get the following message "Strange wispers resonate from the lamp. It appears haunted. Perhaps a higher Conjuration skill will allow me to harness the power of the spirits dwelling within." and no granted ability.
If Conjuration is between 50 and 70, you get the following message "Strange wispers resonate from the lamp. It appears haunted. My weak Conjuration skills allow me to just barely harness the power of the spirits dwelling within. Surely, I can learn do it more effectively." and the ability to summon a Weak Ethereal Imp.
If Conjuration is between 70 and 90, you get the following message "Strange wispers resonate from the lamp. It appears haunted. My solid Conjuration skills allow me to harness the power of these spirits proficiently. Perahps I can learn do it even more better." and the ability to summon a Strong Ethereal Imp.
If Conjuration is between 90 and 100, you get the following message "Strange wispers resonate from the lamp. It appears haunted. My expert Conjuration skills give me a firm controll over the spirits dwelling within. With a bit more study, I can be their master." and the ability to summon two Ethereal Imps.
If Conjuration is 100, you get the following message "Strange wispers resonate from the lamp. It appears haunted. My mastery of Conjuration allows me to harness the full power of the lamp." and the ability to summon three Ethereal Imps.
As Conjuration is improved, the Lamp can be investigated again, with the higher abilities gained once a sufficient level in Conjuration is reached. The message alter slightly from those received when the Lamp is investigated for the first time.
Warlock Torch
The Warlock Torch is in the Warlock Coffer in the Celestial Plane reached from the Pristine Spire in the quest
Another Spire?The Warlock Torch is similar to normal Torches in that it is a light source, but the light shed by it is a different colour and it never runs out, unlike normal torches.

This adds the following effects whilst the Torch is equipped: Fortify Alchemy, Fortify Mysticism and Fortify Alteration, all on self and all for 5 points, Feather for 30 points on self and Shield for 5 points on self.
