It was dark.... and just my luck, a dragon came down to attack me, while i was alone.
It swooped down, and after only 5 hits with my war axe, it was almost dead. I ended up killing the dragon within only 15-20 sec of it landing on the ground.
I was so happy, thinking i finally mastered the way of killing dragons. Suddenly, i turned to my left and saw a Giant (who clearly did all the "damage" to the dragon).
Before i knew it, i was 300 feet in the air.
