- If you sell a Normal, Magic, Rare and Unique item with the same base to an NPC, you get 5 Orbs of Chance. For example, the Unique item Wurm's Molt is a Leather Belt, so if you sell that along with a normal, magic and rare Leather Belt to a vendor, you get Chance Orbs.
- If you sell 2 rare items with the same name to an NPC, you also get a Chance Orb. Sometimes strongboxes contain mirrored items - mirrored items are identical copies of an item, and can be used for this.
- NPC-s sell Orbs of Chance for 1 Orb of Fusing, but that is totally a ripoff, don't use that deal. Orbs of Fusing are more expensive.
