I have just two little tweaks to quest UI to suggest:
The quest screen could remember which tab was shown last time we closed it, to use it when we open the quest window.
secondly, the one I would prefer would be "available + closed".
@PhoenixSword01: it's probably the darkness spell "nightmare" which fills the hand of the opponent with copies of the targeted creature. It is often played with ghost of the past (time)
I've just found that elemental mastery is achieved by having 100 or more hitpoints, no matter what is your maximum.
as using stone skin let me have more than 100 max hitpoints, I did EM with 119 out of 123 hitpoints.
I still find this game very fun, and quite hard
@Keeganx: it depends of your resolution: 1024x768 are 786 432 pixels
while wide screen like mine (1920x1080) are 2 073 600 pixels
