There's a fine line between "potion" and "grenade". Wait. Actually, there's not.

Generated by[]

As well as being collected in decks, this card can also be generated by the following card.

Kabal Chemist


  • This spell destroys one of its controller's permanent Mana Crystals, starting from empty ones.
    • If there are no empty Mana Crystals, a filled Mana Crystal will be destroyed instead.
    • In the unlikely situation where there are no Mana Crystal at all, nothing happens, since a player can never have less than 0 Mana Crystals.


While not looking strong at first, it should be noted that when played at 10 mana you will regain the mana crystal next turn. In the end game, this is effectively a destroy effect without down side. However, even in the mid game there are situations where the tempo loss of sacrificing a mana crystal is an acceptable trade-off for removing a problematic minion.

Another thing to be noted is that this card's mana cost of 4 fits warlock's mana curve nicely since for warlock there are multiple good 6 mana cards, which when used with 4 mana cards allow you to efficiently use all of your available mana after turn 10. Examples of these 6 mana cards include Kabal Trafficker, Siphon Soul, as well as Reno Jackson and Sylvanas Windrunner.
