Weapon A: Obtained by a completing a quest chain that takes you an evening to finish. A final fight that was beaten within just a few days of launch and is beatable by dis-organized pick-up groups wearing i60-i70 equipment. Upgradable by running the easiest level 50 dungeon in the entire game, beatable by duty finder groups with gear ranging from i1 to i50.

Weapon B: Obtained by beating the hardest level of the hardest dungeon in the game. A fight with various phases so difficult that the community actually thought it was bugged and impossible. A fight that took 3(?) months for the first group to defeat. A fight that even now, with instructional videos, in-depth knowledge of all the mechanics, and a nerf to the fights hardest gimmick, takes an average group of very well geared players at least 15 hours of practice to beat.
