In our current game, we have the following enchantment project for the defensive talisman of one player. It seems quite potent, and we could really use veteran players insights on the subject.
On Arm5 p83, it is said that a magus can automatically recognize the hermetic Form of a spell being cast with firm words and bold gestures (it needs a roll if the words or gestures are subtle or in other circumstances).
The goal is to make a independent object that is capable of detecting casting in the same way, and react accordingly.
Here are the details of the object enchantments :
The first effect is
It gives the independent item sight and hearing (Arm5 p112). This effect aims specifically at detecting the forms (Auram, Aquam etc.) gestures and words at range.
Base 2, +1 Concentration, +5 sustain concentration, +4 vision, +1 for 2 uses/day
The second effect
The effect is directly inspired by “Know the power” from Through the Aegis p108. It collects the informations from the first effect and dispatch them to the next effects.
Base 3, per/mom/ind +10 unlimited +3x4 linked trigger
The next powers are still to be finalised but could be anything from creating defenses in case of physical attacks (herbam, terram…) or trying to cast a wind of mundane silence to act as counterspell (in case of mentem, vim, …)
I think our concerns about this item technical legality can be summarized by two points :
- Can an enchanted independent object do the same thing as a magus on Arm5 p83 ? (recognizing spells being cast)
- If the answer is yes, then the next question is : are the guidelines we used there sufficient or do we need to use other effects to achieve the same thing ?
Any other comment is of course very welcome.
(By the way, we already thought about binding a spirit or ghost that could more or less do the same task, but we think that it has its own problems)
Thank you for your insights
