If you like collecting mounts in World of Warcraft, there are numerous mounts out there that you can add to your collection with ease. This list, however, contains some of the most difficult flying mounts to obtain in the game due to extremely low drop rates, large time commitments, or other factors. While there are lots of other mounts that are hard to obtain not included in this list, these mounts definitely deserve to be classified as difficult to achieve.
Violet Proto-Drake Mount
The Violet Proto-Drake mount is one that is difficult to obtain not because of a low drop rate, but due to the extreme amount of time and effort that is needed to obtain it. Not only will you spend countless hours during the special holiday seasons earning the required achievements to work toward this proto-drake, you will have to wait a minimum of one year to actually obtain your mount. This is because the required seasonal achievements are spaced throughout the year. If you work diligently earning these holiday achievements without missing any (requiring you to wait even longer than a year for that particular holiday month to come back around), after your year of traveling Azeroth you will receive the grand achievement of “What A Long Strange Trip It’s Been.” You will finally have your Violet Proto-Drake mount!
Blue Dragonhawk and Red Dragonhawk Mounts
The Blue Dragonhawk (Alliance) and Red Dragonhawk (Horde) is awarded once you have earned 100 mounts, earning you the “Mountain O’ Mounts” achievement. This requires a lot of time, money, and energy that many people do not want to put forth. You will receive lots of other achievements along the way and have a nice selection of ground and flying mounts, but plan on making your Dragonhawk mount a long-term goal. Characters that have been around since earlier expansions may find this easier, since lots of reputation and mounts required for the achievement have probably been accumulated over time unintentionally. This is definitely an achievement that can’t be completely quickly, but the exact amount of time required for it is up to the devotion and time commitment of the player. It could end up a much shorter or longer wait than the Violet-Proto Drake (which takes a year.)
Time-Lost Proto-Drake Mount
The Time-Lost Proto-Drake you need to kill to loot this mount only has a chance to spawn. The Time-Lost Proto-Drake and another drake, Vyragosa, share a spawn timer. The exact time isn’t known, but many people speculate one of the two drakes will spawn ever 6 to 12 hours in the Storm Peaks. Another problem with getting this mount is that if the Time-Lost Proto-Drake is not engaged in combat within approximately 15 minutes, it will then despawn. There are lots of discussions, strategies, and maps found here for those interesting in obtaining this rare mount.
Onyxian Drake Mount
The Onyxian flying mount drops off of the raid boss Onyxia. This drake is so hard to obtain simply because it has an extremely low drop rate. The drop rate for the Onyxian Drake is approximately 0.2%, although there are reports that the drop rate has been raised to a 1%-2% drop rate. Since this raid can only be done weekly, you will have to spend many weeks killing Onyxia before you see the mount drop unless you are ridiculously lucky and don’t have someone ninja loot it off her.
Green Proto-Drake Mount
Before you can start trying to obtain this mount, you must first become revered with the Oracles in Scholazar Basin. Then you can buy a “Mysterious Egg” once a week from their quartermaster. After the seven days is up, you can click to open your egg and see if your proto-drake is inside. With approximately a 2% drop rate and only being allowed to buy one egg at a time, this drake can take many weeks to obtain. Maybe if you’re lucky you wont have to go through a dozen or more eggs to earn your mount.
