Here's some questions for clarification for some af the cards:
Secret Vis Source (Resource)
Does this bonus only apply when you actually literally "gather" vis or does also apply to vis being extracted.
Wind of Mundane Silence (spell)
The spells that were in the item and are returned to the players library - are they to be regarded as active or inactive?
Jupiter's Bolt (spell)
Is the Item or Spell to be discarded decided by the targeted player or the one casting this spell? In all the other similar spell it is stated explicit whom should decide.
Aegis of the Sanctum (spell)
Can this counterspell only protect against spells directed at the owner of this spell or can it cancel a spell effect not targetet at him/her? The card doesn't state that it is exclusively defensive, but my logical assumption (knowing ars magica) is that it wouldn't be effective in other circumstances.
Can this be target on other players installed spells? IMO no, but we've had our doubts.
Fool's Gold (spell)
I'm not sure of the use of this spell - why would one want to spend a spell on something you can naturally do without the spell?
Confound the Connection (spell)
The explanation seems self-contradicting. The spell is in effect a number of rounds equal to the amount of vis planted on it, yet the vis is removed in the beginning of each turn and discarded when it is emptied of vis - that would make the spell duration the amount of spend vis minus one, right?
I know this last one is a bit pendantic, but couldn't help it...
Hope for your opinions!
And if you haven't yet tried it - go get your creations tested at the Tribunals!!!
