If you are ordering the expansion, make sure you do not have an unclaimed Darvual Crystal. Last years expansion gave you all claim items, even ones you had claimed in the past. I would expect this expansion pack to do the same, so make sure you have claimed it so you can get it again.

Darvual Crystal:
Elixir of Refreshment x10
Elixir of Replenishment x10

*Don't forget you can handle these elixirs to Mirao and he will trade it out for the other. Ex. Give him one refreshment, and he will give you back a replenishment.

These are great "OH SHIT" potions to have around for raids. I used 7 of 20 mana pots on Aithzarx in the past year.
