Find at least 3 Elixers of the Witch.

Guide
The Elixirs are all hidden in the caves during the "The North" level. These caves are only accessible by Lyra who will have to dismount off Iorek to explore the caves. Counting from the first cave in this level, the first Elixir can be found in the third cave. The second is in the very last cave before you fight the witch (the cave in which two duck/chicken crossovers attack you). The third is given to you when you beat Queen Vala.

Defeat the Shaman Boss

Guide
Storyline achievement. You will get this after beating the first boss in the game. He shouldn't pose much threat to you.

Defeat the Tranq Tank Boss

Guide
Storyline achievement. Do not attempt to attack the tank before it has released an electric charge, as it will damage you. When it fires it's electric charge, make sure it misses you, as it will damage you. Running in circles around it is very helpful. When it has fired a few times, it will power down. Run over to it, press Y and, when prompted, mash X to tip it over, then attack it. It requires 4 tip over cycles in order to beat the tank. This boss is not that hard as long as you keep moving.

Defeat Queen Vala

Guide
Witch Dominator:
Storyline achievement. Get as close to Queen Vala as possible and swing wildly and blindly at her. Use the white glow below her as reference to where you're at in comparision to her. Once you've hit her a few times, you'll be prompted to hit the Y button in order to perform special Iorek vs. Witches action. Do this whenever you get the chance, as it will drain HP from her. After you beat her, the achievement will unlock.

Defeat the Samoyed Hunter Boss

Guide
Storyline achievement. This boss is quite easy. Just ignore his dæmon as much as possible, and keep on chasing the boss instead. Run up to him, hit him a few times, and let him 'teleport' to another position. Rinse and repeat until he's a goner.

Defeat the Flame Thrower Boss

Guide
Storyline achievement. You cannot hurt the flamethrower while his flame is lit. Just run in a large circle around him, avoiding his flame and the other guys shooting at you. Lyra will be making a huge snowball for you to hurl at the flamethrower. The timer at the top of the screen shows how long it'll take before the next snowball is ready. When it's ready, jump over the fiery gap, and hurl the snowball. You'll then be able to hurt him a little bit. You will have to hurl a total of 4 snowballs. Not a hard battle, but a lengthy one.

Defeat King Ragnar

Guide
Storyline achievement. King Ragnar is extremely easy to beat. You have to successfully hit a series of buttons in order to either be in Defence mode or Attack mode. Both modes requires you to use a combination of buttons, but in Attack mode, you will be on the damage dealing side. Make sure you do not miss the series of buttons! After damaging Ragnar enough, there will be another series of buttons where the bears attack each other. Succeed in hitting the buttons, and you will beat him.

Defeat the Zeppelin

Guide
Storyline achievement. At the end of the last level, when you reach the fire hurler, you must fight off both hunters and witches, while the fire hurler is prepped. Once it's up and running, you will have to interact with the fire hurler and press a series of buttons. The first ball of fire will kill a bunch of witches, and shortly after the zeppelin will appear. You must once again fight hunters and witches, and fire with the fire hurler once more. This ball will hit the zeppelin. The achievement will pop immediately.
