There are so many achievements in WOTLK Classic that give must-have rewards, like a five percent XP ring or your own personal Bambina pet, today I would like to talk about some achievements that highly recommended to complete with the amazing rewards, like pets, mount, ect. One of mounts even has 310% speed buff, you can not miss it.
Venomhide Ravasaur
First mount is for the Horde only, Venomhide Ravasaur, obtaining this gorgeous mount will take you 20 days of hard work, but it is totally worthy, and you'll be working towards the Loremaster at the same time. Lest you forget, Loremaster gives you one of the rarest and most impressive Tabard in WTOLK Classic.
Higher Learning
This is the perfect time to brush up on your wow history by finishing the Higher Learning achievement, collect the eight highly contested books around Dalaran and you'll get a permanent teleport book to get to the Violet Citadel secret room, this is the only possible way to get the large Kirin Tor Familiar pet.
Dread Pirate Ring
If you really want to stand out, you've got to get the Dread Pirate Ring, this is the inconceivably rare fishing heirloom with the five percent XP buff, this is also a great way to work towards my personal favorite Salty title achievement, rewards are so fun, even it's hard to be Salty.
Perky Pug
But the cutest achievement pet in WOTLK Classic is missing, Perky Pug was supposed to be a reward from grouping up using the random dungeon finder, but Blizzard took him out. I really hope Blizzard bring back our Perky Pug.
Plagued Proto-Drake
Remember that easy 310% speed Mount from the intro is the Plagued Proto-Drake from Glory of the Raider, Blizzard has lopped three achievements off, so obtaining this mount will be much easier. Getting Plagued Proto-Drake can be your biggest priority, so start working on the achievements now! By the way if you don't have enough gear for the Raider achievements, do the Glory of the Hero achievements, for the impressive Reigns of the Red Proto-Drake.
Titanium Seal of Dalaran
In between lockouts, it's a great idea to fish up coins in the Dalaran fountain. Collecting all the coins gives The Coin Master achievement, and you'll get the Titanium Seal of Dalaran.
Coin Toss
What's the most you've ever lost in a coin toss? I hope you didn't lose Bambi in a coin toss, because she's the reward for collecting unique pets. If you did Gambler away, at least you have the Reeking Pet Carrier from unique Cats, pet skunks are just as cute as fawns right?
Tabard of the Achiever
I know something even cuter as well, The Tabard of the Achiever, from collecting 25 Tabards, for example maybe you want to get violent, you can grab the Brute Force Tabard from winning 300 arena games. Anyway there are tons of awesome Tabards to collect in Wrath of the Lich King and you do not have to spend tones of WOTLK Classic Gold on it.
Black War Bear
While you collect mounts, don't miss out on the most impressive achievement mounts in the game, the Black War Bear, can only be obtained from raiding all the capital cities and killing their leaders.
Mysterious Egg
If you can achieve revered with the oracles, you'll be able to purchase a mysterious egg seven days later, the egg will hatch and inside could be one of four rare mini pets or the stunning green Proto-Drake.
