• Enemy and Chest Drops:
Feo can randomly drop from enemies, chests, and other loot sources.
• High Elite Density Activities:
The Pit, Nightmare Dungeons, Kurast Undercity, and Lair Boss farming are useful options because they provide many enemies and reward sources.
• Jeweler Crafting:
You can craft runes at the Jeweler by using three runes of the same type to receive a random rune, giving you a chance to obtain Feo.
• Trading:
Feo can also be obtained by trading with other players.
• Runeword Farming Strategy:
The best method is to farm high-density endgame activities, save useful runes, and craft or trade duplicates when looking for a specific Rare Rune.
