Cursed Obsidian Altar
The altar is a large, humanoid-sized slab of pure obsidian, carved with intricate runes and sigils. Staring into the brilliant blackness of its surface is almost overwhelming. There is an evil allure to make a demonic offering here, but of what you do not know.
General
The Cursed Obsidian Altar is located in the remains of the Inquisitor's Tower in Blackthorn. While it does not sell anything directly (the Abyssal Cultist does that), it will exchange your items for varying levels of hellish gemstones: Jewel Infernal, Jewel Abyssal, Jewel Diabolic, Jewel Unhallowed and finally the Hellish Tourmaline. You can also use the altar to transmute 5 jewels into 1 of the next largest denomination. A wide range of items and equipment are accepted, mostly consisting of boss drops and crafted items.
