This has to be the best way to kill a dragon in Skyrim. If you can spare 21 seconds of your time, watch this video that some resourceful gamer added to YouTube showing their simple but devastating method of killing a dragon by knocking out a full half of its health points before it has even begun to fight you.
Okay, so the creature didn’t die and therefore he technically didn’t “kill it” exactly, but if the guy’s character is of a reasonable level for that point in the game then the fight’s more or less one with the disadvantage he’s inflicted upon the beast before it had even begun to attack him.
It is true of course that this dragon starts out in a stationary position whereas others begin a confrontation airborne. It would be absolutely fantastic if the fight had begun with the dragon in the air and when it had landed, the character had somehow managed to managed to hide himself from it – stealth? invisibility magic? – and then gone up behind it, jumped on top of its head (or I suppose just to its wings, legs or ass would work as well) and delivered the critical sneak attack. Perhaps someone could even do that twice in succession and kill it like that?
So whatever other good ways you may have discovered of killing dragons that some people might find helpful, it would be great if you could let us know by commenting here or posting on the Skyrim Dragon Killing section of our forum. Weapons, tactics, magic, anything would be great. You never know when something you know might help someone else.
