I had one such moment earlier. I am doing the Stone Rituals for the Skaal in Bloodmoon... and I came upon the quest required by the Tree Stone...
Needless to say, I was horrified at having to defeat five spriggans simultaneously with the difficulty set to 100.
I made an enchanted ring, named "The Ring of Volcanic Blasting," that dishes out ten points of damage for 15 seconds in a 20 feet radius, on target
I also used a Golden Saint soul... so the thing had 400 charges, which meant a total of 10 nasty blasts of fire.
In sneak mode, I approached the circle of Spriggans and Rickling and hit them with a wall of flames. They all died over the duration, and, of course, ressurected themselves. So I blasted them again. This time they all began towards me, but I levitated out of reach, the flames took hold, and they died once more.
I flew off a distance, descended and went back into sneak mode, and then proceeded to take on the spriggans one by one with Skull Crusher.. and of course they were on their last lives, so they couldn't bite back
This qualifies as one of my more enjoyable experiences in the game because it actually required a bit of thought
Okay... well.. some stinky cheese too
So what are your favourite battle moments, or occasions where you have outwitted an enemy?
