I had just got Shadowmere for the first time, after my friends had told me that he is completely? invincible (which he is in battle), so I was like "Awesome".
So there I was on my apparently "invincible" horse when I decided to jump off a mountain to reach my quest objective quicker.. After enjoying the 3 second airtime on my flying horse, as soon as we touched down I flew of Shadowmere to the sound of him dying, only to continue to fly another 20ft on my own, land on top of my quest objective and get up as though nothing had happened.

Shadowmere was dead.
And I was mad.

The first time a slow two-handed user attacked me with a forward power attack, very slow. Took about 70% of my health away. Then, before I could even open my inventory, death animation. O_O

my wtf moment was not watching where i was going and fell off a huge cliff on Shadowmare and I hit the ground and slid off horse and watched it go flying the death music started but I got right back up... never saw shadowmare again lol

I walked out of Whitefun after I had defended it from the Stormcloaks. I looked up and saw my horse in the sky. It then fell to the floor and died.

Does anyone one want roast Horse haunch? I got plenty to spare

I had a wierd incident with my horse at Windhelm. I rode my horse up to the front gate and climbed down. Then, suddenly, my horse turned 90 degrees to the west, then promplty walked off the bridge.

No guards, but I've had this happen a couple of times with other NPC's in Whiterun, like the little girl that runs around town, and the guy (I forget his name) that gives you a quest to find his father's sword.

When I first saw a Forsworn Briarheart up close I stood over him going wtf........and cringing and going eek at his Briarheart and the hole in his chest held together by leather straps were his heart was before the Briarheart.
That is a facinating procedure that they do, but creepy and painful looking.

The heart isn't beating. They are killed before it happens and raised by hagravens.

I was in riverwood, I killed a chicken and for some reason the guards started attacking the owner of the chicken (a guy and girl) killing them both and then the guard started to attack the children which was a ([censored] YES) moment.

Right, did'nt know that.

A annoying one.

I paid off Bhadrak The Steel Hearteds dowry and she became my follower.
Went to the place full of witches and hag and hagravens etc were you find Illia and she went weird.

I used chain lightening on the opposite side of the room and she got hit and sometimes attacked me.

Her tactics got mixed up. She was going at distance enemies with her sword and shield and trying to mellee people with her bow.

She died repeadly. So many times.

The last time I tried she fought normally against he living after I cleared out the enemies before she could slam into a wall again, went into a room with a skeleton, and got stuck trying to draw her sword and shield, going ow, ow, ow repeadly and flinching while holding her bow.

Every time she met a skeleton she freaked out and stood there going ow, ow, ow repeadly when it hit her and not fighting it at all.

I reloaded, sent her home and went on alone.

That has reminded me of when I was running along the road and I saw a dead bandit on the floor. I decided that I would borrow his horse as he was not going to use it any more. After a short while I went to get uff it and all of a sudden the horse was pulled up the road by an invisible rubber band.

I heard you can kill a briarheart by pickpocketing his heart.

I had a weird glitch just before. I was riding around and came across a noble beside his horse. I nudged the horse away from him (still on my horse) before he got on it. He sort of mounted it in thin air and sunk up to his knees in the road. Then he started spinning around faster and faster and eventually disappeared. I think maybe he got thrown away by a physics glitch.

I have two. The first one happened outside of Windhelm and a little ways to the west, I was riding my horse through the snow when some wolves spotted me and started to give chase. I didn't feel like fighting at the time so I had my horse run full speed towards the city only to have some brown blur go flying past my screen...It turned out to be a horse that had died in a totally different part of the map.

The second was on a mountain road outside of Solitude. I was riding my horse along the path and had just turned onto a steep (downwards) road when I spotted a cute little bunny. I rode past it and didn't think anything of it...till I heard a horrible little screech and cracking sound...I turned around to find the little rabbit dead and sliding and slightly bouncing down the hill. It seems that the road was just a little too steep for its little hopping and gravity killed it.

I found Faendal, dead, in the middle of Riverwood. Dorthe was rifling through his pockets. I thought to myself "You murderous thief! GUARDS!!"

I have just seen a Giant trying to fly a dragon. The dragon took off and the Giant fell to his death.

It happend so fast I could not get a screenshot. I reloaded it hoping that I might get another chance but sadly not.

Decapitating a dude... with my MACE...

Never gets old!

It is essential to them though.
If you pickpocket a Briarheart of his briarheart, he falls to the floor dead.

More a swear filled rage moment.

Fighting Alduin.
Realised some moron made Alduin and Paathanux so close in colour and shape you can't tell them apart properly when they are flying.
What, they could'nt have made one bright blue or something?! A stripe a pattern, anything?! Anything to stand out when they're charging round the sky faster than your spells and shouts go!
So many reloads.
I hit Paathanux by accident and he attacked me once.
Alduin bugged out repeatedly. Hit him twice and he bounced off at the third go and bounced into the air, then went stiff and slowly plummeted to the ground. Not moving at all. Or he got stuck in the sky. Out of reach.
Finally pinned him down with constant shouts and carved him up with dawnbreaker.
And Paathanux never shuts up about using Dragonrend in the fight. I know, you don't have to remind me every 5 minutes!
He is like the priest Verdelet in Drakengard 1 who spents entire flying and on foot sections repeadedly telepathically telling you to do things and kill the goblins, kill the orcs, kill the ogres, etc.

Gorey wtf.

Went into a vampire den and saw 2 hands on plates they were having for dinner, lol.

I was in the Labyrinthian, clearing out the dungeon as you normally would. As I was walking, I saw a massive hole in one of the walls there that the devs had failed to patch up when making the game, where i could see underneath everything in the world. Out of curiosity, I stepped into the hole. For a moment or two, i was walking on nothing, but then, my character started falling downwards infinitely.

Then I was like "OMGWTF?"

Become Ethereal ended right when I hit the floor

I was killing a master necromancer in the Morvunskar. I really had a problem with that, I had been killed by him more than 10 times and this time I had to kill him. I was really killing him, he has started to say: don't kill me, enough! and the stuffs like that, suddenly boom! I was moved to a garden where I met Sam! I was exactly like WTF!

I was in a dungeon grabbing some phat lootz when a random stormcloak soldier comes running in, hits me with her hammer then runs back out.... I found her laying outside full of arrows, I geuss I didn't kill all of the draugr that were outside the dungeon.

This.

Fighting a dragon, and another shows up. Then another, and then two more. Five freaking dragons, I barely made it out alive. I had to use like 40 potions.

Facing three trolls in a cave and after killing two of them and thinking my almost dead character is about to die at the hands of the last troll i suddenly found myself back outside due to the troll having pushed me out the cave exit. Laughing to myself at my unbelievable luck and after a bit of healing i headed back in the cave and finished off the last troll who had already fully healed.

Its amazing how different and full of surprises encounters are in Skyrim.
