[Magiclysm] Being grabbed makes SOMATIC spells harder to cast

[Standing-Storm]

Summary

Mods "[Magiclysm] Being grabbed makes SOMATIC spells harder to cast"

Purpose of change

Follow up to being mute making VERBAL spells impossible

Describe the solution

Make an EoC that increases the Difficulty of spells from the Magiclysm schools by 10% of the total intensity of any arm grabs you're suffering. This equates to roughly +12% failure chance per 10 intensity of arm grabs.

A second EoC increases the Difficulty of spells from the Magiclysm schools by 20% of the total intensity of any hand grabs you're suffering. This equates to roughly +24% failure chance per 10 intensity of hand grabs. Hand grabs are generally pretty rare, but be careful if something gets a hold of your hands.

These stack.

The SUBTLE_SPELL flag makes you immune to these increases.

Describe alternatives you've considered

Testing

Spells' casting Difficulty is properly increased. Only affects SOMATIC spells, only from Magiclysm (also tested with XE SOMATIC spells, which were unaffected), and only when arms or hands are grabbed.

Additional context

I thought about doing a code solution like for the VERBAL flag, but I think there needs to be better JSON-derived supernatural power usage specifications first. For example, SOMATIC is used in both Magiclysm and Xedra Evolved, but for Magiclysm's wizards, I envision their spells requiring sweeping gestures that require completely free movement to be sure of execution. For Xedra Evolve's Paraclesian fae, SOMATIC is still appropriate because heavy gloves should penalize their spellcasting, but the actual movements are probably just a flick of the wrist or a single gesture. And meanwhile, Xedra Evolved's hedge wizards should probably be completely shut down by a grab of any intensity.

This provides thematic space for someone to add the equivalent of Power Word spells (high Difficulty, high mana cost, sub-one-second cast time and doesn't have SOMATIC on them). It may well be me--I have some ideas already.

Brilliant breakdown of different needs by spell caster type

I just realized based on my work here I can implement "magic is easier in appropriate terrain" for paraclesian fae.
