So I opened around 15ish locks and received the following:

Arcane shard

Bonecrusher of brawn

Slaterock for mage.

Dragon Hunter of Brut, lv 46 for mage.

4 sacks of jewels.

I was wondering if anyone managed to loot the new mythic weapons while opening the same amount of locks? Do I need to rub my device on a leprechaun before hand?
