Add a new Dynastic Rule to the Ruleset.  Call it “Wards” and give it the following text:

Each Apprentice may have a single enchantment affecting their bench, tracked in the GNDT under the “Ward” column.  The legal values for a Ward are:

Null
Suppressive
Hardened
Trapped

An Apprentice’s Ward defaults to Null.

An Apprentice with a Suppressive Ward cannot Cast or be affected by any Spells.  Whenever their Workbench is Manipulated, their Ward becomes Null.

An Apprentice with a Hardened Ward cannot Cast or be affected by any Spells.  Whenever their Workbench is Manipulated, their Ward becomes Suppressive.

If an Apprentice with a Trapped Ward has their Workbench changed by another Apprentice, their Ward becomes Null and that other Apprentice has the first Rune in their Workbench changed to ‘X’.

Append the following text to the to the Rule entitled “Basic Spells” if it exists:

The Spell “Panic” has “SOS” as its Activation Sequence.  Its Effect is “Your Ward becomes Suppressive unless it is already Hardened.”

The Spell “Booby Trap” has “TRAP” as its Activation Sequence.  Its Effect is “Your ward becomes Trapped.”

Set each Apprentice’s Ward to “None”.  Set the Artisan’s Ward to “Trapped”.
