Yes the rules of ceremonial casting. Thanks for remind me that.

What is your advice of this spell :
Invoke the necessary components of the geometer
Creo Terram (aquam, herbam)
Range : Touch
Durée : Sun
Cible : Ind
You invoke minerals and purified metals in powder (précious ans non precious)
with pure water, oil and incense.
Things needs a geometer for ceremonial casting.
Base 15 +1 touch +2 sun +1 herbam +1 aquam
Level 40
Not easy to travel with all components.
