Soul Canopic

From HGWiki

Drop from killed creatures and random loot spots and can be discovered as secrets in the hardest areas of the module (currently Limbo).

They drop as various types depending on the quantity of Canopics present in the item and can be combined into larger quantity single items (5, 25 & 100) when you have enough using the !combine command making management and inventory control much easier. The 1 and 5 value items drop from encounters, loot spots and secrets, the 25s drop from the bosses at the end of Limbo Part 2 and the 100s can only be created by combining.

They can be used to purchase eXtremely Rare loot through conversations with Ixion (present in Forge of Ixion) with increasing quantities required to be more specific about the type of item you are purchasing.

Although it IS possible to gain any XR item though a random 50 Canopic deal the sheer quantity of XRs (248 including weapons and books) means it is extremely unlikely you will obtain the one you want through this option. There would also appear to be some scaling in terms of base value in that it is less likely to receive a weapon (even less likely a book) on a 50 roll than one of the equipment items.

The 100 Canopic option allows choice from a specific group of items e.g. Boots, Cloaks, Armour, Shields, etc. Note however it is NOT possible to obtain either weapons or books through this choice.

The 200 Canopic option allows choice from a specific size category of xR Weapons excluding missile weapons or ammunition as there are no xR versions of these. Note: Double weapons (all Large size category) are actually listed in the huge weapons category.

The 250 Canopic option allows you to pick a random xR book although as there are 50 of these the chance of getting the exact one you might want is fairly slim.
