Invisibility to Magic

Invisibility to Magic (minor) by Mr. Twist

This power makes the person invisible to any magic spells that attempt to sense them, or any magic items trying to sense them. This includes the triggering of magical traps, wards, and circles; the person with this power walks right through them. If the mage can sense the character with any of their normal, non-enhanced, senses, they can affect them normally. This also applies to magical scrying or attempts to see the future.

Notes: In a Rifts setting, or any setting with a lot of magic, this power should be major. Otherwise, it should stay as a minor. If even being a major seems not enough, then make the user not able to use magical items of any kind.
