9 mana? An entire arena spell for so little yet incredibly powerful....Sorry Warlock. That's a bit discouraging.

I'm guessing this is an incantation? Non epic so it can be attached to a wand and spammed.....I hope i'm wrong.

This mixed with her plants built in regen, uhhhgggh I don't know how to process this properly.

I would guess commissioned. If you go to their facebook different artists have taken credit for their pieces. Personally I think the artwork in MW is top notch. Far above most artwork in games. There are better pieces than others, but as a whole this is a beautiful looking game.

As a side note to the other strategies because this is very situational:

In a couple games I have played vs a  forcemaster I have purposely put a dispel wand ( not the already built equipment card mind you) in hand as a deterrent for this combo. I find that by just having it, they will be very reluctant to even try. However if they do try you don't have to worry about the anticipatory dispel before the combo because you can just use it instead of card picked. Thus minimizing wasted turns and defensive playing.

Now I say it's very situational because with a strong player this will be shut down fairly quickly. Anyway, just a thought.

I'm guessing they are not readily available due to proprietary reasons. I was able to find a nice wallpaper version of mind shield

Well there you go. Thanks for quick clarification.

Shame about the Necro's staff. I'll more than likely just equip Libro Mortuos and incantation wand. Of course i'll play around with it, but in it's vacuumed state I'm not seeing need to even put in book.  The 8+ rot is too risky to waste an action vs the always useful wand. The quick action Melee +1 with range 0-1 and 2 mana cost is unlikely to make it worth the points unless you specifically played to the staff by hording zombies in the same zone. Generally not a great idea because of area effect spells. Of course I could be totally off the mark, but so far imo the Necro isn't a front line (warlord style) fighter. In most games i'll position my mage defensively while allowing creatures and poisons to rack up. Therefore the +1 melee would become very situational. I bet it's better in a rush skeleton (due to no lumbering) build.

Now the Druid's staff is something different entirely. Only a level 2 compared to Necro's Level 3, 1 less mana , equal dice to necros, the awesome reach factor (vs heavy flying builds), and the awesome 4 mana vine stuck condition. A perfect answer to big creature builds. 
Especially useful because unlike Necro I can envision her as a very good tank, Barkskin (4 mana cantrip, come on!!!) mixed with regen belt and a regrowth enchantment and she is healing 6 hp each round automatically. That's impressive.

If Shaggoth consumes/obliterates a plague zombie, will all living creatures in zone still receive a rot condition?
