1. There are 3 hidden bosses
Down in the Dwemer ruin, Blackreach, there’s a gigantic orb towards the center of the underground cave that’s pretty hard to miss Just look at it and use the Unrelenting Force shout! Suddenly you’re fighting an underground dragon known as Vulthuryol. It’s not really that hard to defeat, but it’s kinda difficult to find. And if you haven’t killed the nearby giant yet, you might get to see a fight between a dragon and a giant!
This one requires the Dragonborn DLC. This boss is a throwback to Morrowind’s Bloodmoon expansionis Frost Giant king Karstaag. To summon him, you must retrieve his skull from the Glacial Cave, placed on the throne at Castle Karstaag Ruins, and you’ll get to fight his spectral form. It’s a hard battle, but if you win you gain the ability to summon the ghost of Karstaag, but only THREE times ever, and only when outdoors.
If you have the Dawnguard DLC, you can fight The Reaper. Head to the Soul Cairn,then in to the Reaper’s Lair – place three Reaper Gem Fragments on the altar, and get ready to fight THE GRIM REAPER!
2. The Thieves’ Guild marks buildings like hobos
Most buildings in Skyrim have a Thieves Guild mark somewhere on them. Here is a chart that explains what they mean:
3. Ulfr the Blind has a blank book
The cave at White River Watch is teeming with bandits as usual for a Skyrim cave. But there is one bandit there that is harmless, and blind. But he loves to read. How does a blind man read? Well apparently with his imagination because his book is blank anyways. You would think he would go for a book written in braille…
4. Forsworn Briarhearts can be killed by pickpocketing the hearts out of their chests
If your pickpocket skill is high enough, you can sneak up behind a Briarheart and rip their heart right out of their chest just like an Indiana Jones villain!
5. Mammoths tended by giants have markings on their tusks
You can tell the difference between a free mammoth and one tended by a giant by whether or not there are markings on their tusks. If you attack a mammoth with tusk markings then you will probably end up being perused by an angry giant. But you are free to hunt mammoths without tusk markings without giant intervention.
6. Dead dragons show up on your map
If the enormous dragon skeleton is too hard for you to find, it will actually be marked on your map.
7. Using fire magic on water makes it boil
Find a shallow waterway and blast some fire at it, the water will actually boil. It may be useless besides that it’s entertaining. Kudos to Bethesda for adding that kind of detail into the game!
8. There are ants crawling on the ground and on tree stumps
Just another fine example of useless yet impressive detail in the game.
9. If you activate all of the etched tablets on the steps up to High Hrothgar, no animals will attack you for 24 hours (real time)
Technically you are supposed to walk all the way up the path to reach the top of High Hrothgar. But of course most up us just run and jump and get up there as fast as we can. But if you slow down and take the time to activate all 10 stone tablets, you will get the temporary perk “voice of the sky.” Of course if you strike first however, the animals will fight back.
10. The soldiers actually do as their told
Once you prove to the Jarl of Whiterun that dragons have returned to Skyrim, he orders his housecarl Irileth to dispatch some guards to Riverwood…
…if you follow Irileth as she leaves Dragonsreach, she doesn’t just disappear or teleport to another room, but walks down the steps and across Whiterun…
…to arrive at a meeting with one of the guards, telling him that he’ll need to gather a few other guards and head for Riverwood.
They converse about how many guards Whiterun can afford to send, what the realities would be of a few guards against a dragon, and the importance of protecting Riverwood from whatever may attack it.
The guard is met by two others, and they leave the town….
…but instead of teleporting to Riverwood, you can follow them all, in real time, as they make the trek (although one may run while the rest stroll calmly). Eventually, all three will arrive in Riverwood…
…and continue treating you the same way they always have.
