Make a trial. The entrance to the instance is a door somewhere. But there are 8 keys needed to unlock. You can find the keys in random locations anywhere, and you can only carry 1 key. When you assemble 8 keys (2 tanks, 2 healers, 4 dps) You can form a team and open the door. Inside you will be granted one shot at a 15-30 / 30-40 / 40-50 / 50+ boss . Your leader chooses which to face. If you die, the keys shatter and you have to start again. If you win, super cool mount for everybody. This trial involves team work, chance, and skill. Ergo it involves FUN. And the reward would be cool because I for one would be envious of those that got the top prize.

FUN!

And yes the keys are nontradable and unique lol (none of this store multiple uniques in your retainer stuff) These are KEY ITEMS. Lol get it? Key items?
