First off, the Dragon Hunter and Dragon Stalker legendary armors were supposed to be included in this event, but
they're nowhere to be found.

If you check the normal and greater glacial chests, this is the only legendary that can be found in the greater glacial chest.

Another thing that kinda confuses me is what about the plat tier version of the ice guards? They aren't shown any where on the boss tracker. Does killing them now add up with the amount of times you killed the non-plat tier version?

Also, how much does the Dragon Flamestone randomly buff stats?
