I'd like to create some "become an awesome beastie/giant" spell/s, but RAW is a bit scant on what the correct magnitudes would be. What do you guys think about Irondboundtome's spells (link https://ironboundtome.wordpress.com/2014/06/24/transformation-into-gargantuan-creatures-part-one/), do you think the levels are OK?
Especially this:
"Form of the Lumbering Jotunn
Muto Corpus 20, R: Personal, D: Sun, T: Ind
This effect enlarges the Magus up to a very large (size rank 10) version of themselves. At this size the Magus is around 60 feet tall, and weighs over 100 tons.
The character’s combat mechanics are greatly enhanced, adding +20 Strength, +10 to Soak, -10 to Quickness. The character also gains the reach and leverage associated with the truly massive stance."
Seems a bit low level for the awesomeness - should I drop a few size ranks?
There's some discussion also here: https://forum.atlas-games.com/t/shrinking-or-decreasing-size-spell/10834/1
I think this seems reasonable: "MoH, p.49., has a spell to grow the target, and it uses as a guideline the idea that you need enough size modifiers to make sure that the magic can affect the "end result". Since each +1 magnitude multiplies the mass of what you can affect by 10, which corresponds to a +3 increase in size, with the basic effect you can grow a target to size +1 (which is still a basic Corpus Individual); with an extra magnitude you can grow him to +4; with two extra magnitudes to +7; and so on."
