I started thinking that Magic Resistance might (almost) be irrelevant if the attacking creature is huge enough – say far larger than “Form of the Lumbering Jotunn“ written previously.
What happens if a creature is so large that it affects the environment and not a single Magus? Perhaps large enough to scoop a room or building sized patch of ground around an opponent in their hand. Or uproot an ancient oak tree and use it as a club? The opponents magical protections are moot, just like when a spell transforms the ground beneath their feet.
It might be akin to Gulliver from Gulliver’s Travels – so large that normal sized humans are like fingers.
Form of the Titanic Colossus
Muto Corpus 40, R: Personal, D: Sun, T: Individual
This spell monumentally enlarges the caster up to a size rank 22 version of themselves, so large that the caster’s fingers are larger than a normal person.
At this size the Magus is around 120 feet tall, and weighs over 5.5 million tons. The character’s combat mechanics are greatly enhanced, adding +22 Strength, +22 to Soak, -22 to Quickness, and radically shifting the amount of damage for each wound category. The character also gains the reach and leverage associated with the truly massive stance.
Requisites are required when cast to transform clothes and equipment, and not all equipment will be included in the transformation. The effect is designed with a girdle as the focus, which is removed to end the effect prematurely.
(Base 3 to utterly change the size of a person although still human up to size +1, +2 Sun, +7 for an additional 21 size ranks)
