Under Saarthal is the first action rich quest of the college of winterhold. In case you are looking to enter Saarthal without the quest you can find Saarthal south-west of Winterhold and south-east-east of Dawnstar:
Early on after you have found Arniel Gane you will have to pick an amulet from the wall. It will cause the gate behind you to close and Tofdir will ask you to figure out how to open the gate again. Simply equip the amulet. If you then turn towards the wall that you took the amulet from you will see something like fire coming out of it. Use fire destruction magic on the door to finish solving the puzzle which will blast the door out of the way.
First Animal Puzzle
For this first puzzle all you have to do is match the turn able pillars to the symbols above and behind it. For instance for the first pillar to the left has must be an eagle:
Change the right row of pillars to an eagle for the first, snake for the second and fish for the third pillar. Change the left row of pillars to a fish for the first, eagle for the second and third pillar.
Second Animal Puzzle
The second animal puzzle also shows the solution symbols above and behind the pillars. However some of the pillars turn some of the other pillars. The left pillar of the set that is closest to the lowered gate turns all other pillars as well. Set that pillar to fish first. The next pillar is the left of the set that is furthest away from the lowered gate, it will turn both of the left pillars. Set this one to snake next. Next you will have to set the right pillar that is closest to the gate to eagle and the last pillar to fish. Pull the lever to raise the gate.
Killing Jyrik Gauldurson
Tofdir will tell you to keep him busy whilst he uses destruction magic to damage the magicka of the orb. Jyrik doesn’t do much damage so I decided to tank that damage. You will quickly be able to kill him after the enchantment on him breaks.
The daedra hearts are harder to collect. There is one in the basement of Jorvaskr (the home of the companions in Whiterun) but if you do want to make any more than one deadric item you will need to find more of them. The best way to collect as many as possible is to go to the Shrine of Mehrunes Dagon. However, to enter you will have to go to the museum in Dawnstar and complete Silus Vesuius’s Quests. You can find the shrine here:
In Valthume there is a dungeon quest as well as the word of power. For the quest you have to find three potions which are marked on the map. They should all be fairly easy to find usually requiring a chain to be pulled in order to enter the particular caves. In the end you will have to kill Hevnoraak who has a lot of health. You can kill him by tanking damage and retreating once you are low on health. You can find Valthume:
Two handed can take a long time to level up in the ordinary fashion. However, if you use the techniques I have outlined below you can solely focus on leveling two handed, speeding up the process significantly.
As with destruction you will want to conjure a creature using the conjugation magic. It is best if you cast the spell that will create the creature with the most health as two handed levels up according to how much damage you deal to a valid opponent. make sure you have some restore magicka potions ready so that you can continues this techniques for a while because on the later levels it takes quite a lot to level up this skill.
The best trainer is Vilkas who can be found in Jorrvaskr (where the companions are located) in Whiterun. Remember that the gold you paid for training can be pickpocketed back as long as it isn’t too much gold (around 2000 gold the chance of pickpocketing approaches 0%).
