Just for the sake of further discussion: when I brought this post up to him last night he cited this part of the rules as his reason for initially believing range and LOS applied for the reveal:

Designer’s Note :
The Enchantment Matrix
An enchantment is a spell divided into two parts.
When you cast the spell, it creates a magical “matrix”
on the target. At this point, it is not fully formed and
exists only as magical potential, with no effect on the
battle. When the spell is revealed later, the caster
“completes” the spell by adding additional power. It
is only then that the enchantment takes form and
can affect the target. Using hidden enchantments,
a Mage can build a web of diabolical surprises for
his foe, which is an important part of the tactics in
Mage Wars!

pg. 21 in rules V2

He feels that the terms "fully formed" and "completes" suggest that the spell is not completely "cast" until it's revealed thus LOS and range applied.

I suggested these event progressions as a way to possibly understand

Enchantment is cast and goes through: Cast Spell --> Counter Spell ---> Resolve Spell

The resolution here being the enchantment is successfully played hidden.

Once the reveal happens play progresses.

His next question was then does the enchantment go through: Reveal Enchantment --> Counter Enchantment --> Resolve Enchantment meaning... Can you counter an enchantment?

At that point we decided to drop it and just play.

Feel free to direct me to a different post. I looked but couldn't find anything covering it.

The friend I play with and I are having a debate over this issue. I hope someone can clear it up for us.

My understanding:
Enchantments have two phases: Cast and Trigger/Reveal.

-The Cast phase has to take into consideration validity of target, LOS, range, and casting mana cost.
-The Reveal phase has to take into consideration trigger (if any), reveal mana cost, and the consequences/choices of the reveal.

What that means to me is if I cast Block (range of 0-2) and then the creature moves a third zone away, when the trigger happens and I must reveal the enchantment I can still pay the mana cost and use block. It doesn't destroy because it is out of the casting range(because it has already been cast) . Same idea with LOS.

Dug around rules v1, rules v2, FAQ, and the forums. My friend's opinion is that if you move out of the range of the enchantment it destroys if you reveal unless you get back into range or back into LOS.

Help us out here!

Thanks!
