Accessories from Mirror Rifts

I finally got some accessories from Mirror Rifts. First, I ran 61 Basic type mirror rift (mostly Lv.70 dungeons) to get my first accessory. Then, I ran ~17 Earth type (Lv. 62 dungeons) to get one, and then only 5 Fire type (One each from Lv. 60 through Lv. 68 dungeons) for one. The stats for the ones from the Earth & Fire types are not that great in their stats.

The moment you know you are getting an accessory is that the final boss of that dungeon still remains even after the explosion. Then, it pops and drops the accessory. I thought it was funny...

This is when no mirror accessory is dropped in most cases. (play the video)
