After the Storm
Spell Casting and Blessing Invocation
Spell casting requires words, gestures and the appropriate mental state.
The written form of a spell looks like complex musical notation as it conveys all these elements.
Spell casting cannot be done covertly unless the specific spell notes it.
Casting without gestures adds a Challenge Die and automatic failure to the spell casting pool.
Casting without words adds a Challenge Die and automatic failure to the spell casting pool.
These effects are cumulative. This makes it effective to gag and bind a wizard (two challenge dice and two automatic failure results into the spell casting pool).
Spells and Blessings that “target” someone, such as those against Target Defence require seeing the target. They are thus ineffective against invisible targets (unless magical sight or other means helps locate), in total darkness or if blindfolded.
Some theorize that the words and gestures are really assitance to the mental state, but no mortal caster of the known races is so adept as to be able to safely dispense with them.
Blessing Invocation relies more on words (prayer). Invoking a blessing without gestures adds a misfortune die, while invoking without words does add a challenge die and automatic failure.
For both Spells and Blessings, gestures may be made holding an appropriate implement be it a wand or warhammer (if Sigmarite) etc.
