I've burned down human towns, and single handedly ripped through 5 goblin fortresses, one after the other, not going to sell loot or get any one to help me. Legendary in armor and shield using, ambushing, throwing, and swordsmanship, i have yet to find an opponent worthy of my "ultra-might". I once was running through a cave, in search of anything interesting, and when your just holding down the arrow key, time goes by pretty fast ; i took 4 steps, not one of those steps i stopped to notice there was a minotaur boss below me. By the fourth step i realized i had engaged and slain a minotaur by accident. Right now i'm looking for a dragon to fight, but i fear that it may end up disappointing me.
If anyone knows of something so brutally powerful, be it a race, band of thieves, monster or anything, please say so. In the words of Achilles :
"Is there no one else! Is there no one else!?!"
(again, sorry for the self praise, and the multiple movie quotes)
Prepare a room full of elephants. On one side of the room, there is a drawbridge. Before the drawbridge there is a pressure plate.
Enter it with no weapons and no armor. If you survive the initial fall, kill every elephant.
