It is persistant effect that is always on, resulting in a Usefulness of 5. Â It has the normal diaklave abilities plus an Essence 3 Solar Charm, resulting in a power 4 effect after all calculations. Â It would have a Game Impact of 4, as it does do some really remarkable things to the danger level of enemies. Â It would have a Script immunity of 3, just to allow it to survive.
It would be a level four artifact, and it would require a commitment of 15 motes+any Essence Drawback.
Yeah, I gotta agree with you Seiraryu... The other thing is that if you accumulate more successes on the roll to create the artifact is that you can reduce the number of motes required for commitment.
