It also has an interesting animation when the pet is summoned, it follows the player character around and “nibbles” at their feet. The Nibbler has a classic zombie-like look with rotting green skin, exposed bones, and a missing eye. This pet is extremely rare and sought-after due to its unique design and animation. The rarest pet in Diablo 3 is the Nibbler pet, introduced with the release of the Rise of the Necromancer pack in mid-2017. Once purchased, the Falcon Wings will be available for all characters on the account, and will be visible in the character inventory in the ‘Accessories’ tab. You will need to spend the Gemstone and 700,000 gold per character to purchase the wings. Once these are achieved, you will be rewarded with an “Aether Gemstone”, which is used to purchase the wings from the Vendor Vendor in the center of the Crucible of the Cosmos area in Clucifix Hold. This achievement is acquired by having a character of level 70 in all classes, completing the game in the Adventure Mode, and having all the Seasonal Achievements. Cathedral Level 2 - From here you will back track to reach Leoric's Passage.In order to get Falcon Wings in Diablo 3, you must first obtain the well-known achievement known as “Eternal Collection”.You will end at Leoric's Manor teleport point. Northern Highlands - Head here to find the Northern Highlands, and Leoric's Hunting Grounds.Southern Highlands - Head here to find find the Clan of the Moon Cave.(My personal preference is to run them in this order.)
