Intercede!; Catch-all ability for defending and resisting

[kirbwarrior]

I was playing another system a while back and my character's signature move from that system was to use a spell to resist (or defend) an attack or ability. She could use it on herself or anyone within the abilities range.

I like the idea a lot, and wanted to build it in gurps. My first thought was to take it as a wildcard skill. Will is 5pts per level, HT with no FP is 7pts per level, so the price seems close enough (pros and cons probably balance out). However, I'm not certain it's actually fair, or even sensible.

Is there a way to use this ability to help others? Is there a better way to build this power? I have looked over many of the books, but I'm not really sure where to look or what to base it on.

Thank you ahead of time.

You say "spell", so the first question is "what magic system"? Standard magic, magic-as-powers (individual spells built out of Advantages, like super powers), one of the systems in Thaumatology, RPM, Sorcery, etc.

In few of those systems do you need a skill that can be any skill (a wildcard skill).

To make a spell an Active Defense, it generally needs a trait for that purpose. A "Blocking spell" in standard magic, or the "Reflexive" Enhancement and "Active Defense" Limitations for abilities in magic-as-powers or Sorcery. See also the "Defending With Powers" rules in Powers (p167).

Wildcard skills aren't really designed to to represent supernatural abilities. At least I've never seen them used that way (even Wizard! from DF1 is non-spell skills).

This sound more like an Affliction with the advantage enhancement. Depending on how exactly this power manifests, this could grant extra Will, HT, DR, Enhanced Dodge, or just give them Luck!

That would be the general method for building a buff of some sort to make the target better able to defend themselves. Depends on how you interpret "defend".

Also, some concepts might get some mileage out of Affects Others -- perhaps the mage can extend their magical shield, psychically boost someone else's Will with their own, etc., while also enjoying the advantage themselves.

Assuming we're talking about standard Magic, is there an accepted general method for turning some spell into a Blocking spell? Reflex works if you have time to pre-cast, but how about on the fly, sort of the way Throw Spell turns other spells into Missile spells? What would be a fair cost for an advantage that let you "reflex-ify" any spell, during combat, fast enough to act as a Blocking spell? (One place to start might be Compartmentalized Mind, limited to defenses only, or "Reflex Only". But it seems like it would take several levels to get both Reflex and most choices for the defense spell to become instant cast.)

Anything other than "Sorcery" (or advantage-based) is much easier to slap something into. I could see Verb-Noun magic being able to do this without any changes. I'd love to find out how to do it with advantages if possible.

Wildcard skills can do quite a bit. Wildstyles are a variant and can have supernatural skills. And Magic! lets you use any magic in the default system.

Those are all good ideas for setting up protection ahead of time. I was trying to think of a way to be able to do it in response.

However, now that I think about it, Word magic (both Verb-Noun and Realm) actually seem like they can mimic this idea (at a large penalty). Maybe it could be built as a technique for that system...

The Reflexive Enhancement (Powers 109) is the go-to modifier to turn switchable abilities into reactive defenses.

Active Defense (Powers 112) approaches the problem from the other direction. It's a sub-category of Requires Attribute Roll, so it takes an always-on defensive trait, and not only makes it require an attribute/skill roll to work (like a Parry, Dodge, etc), also requires awareness of the threat. DR works all the time; DR with Active Defense only flickers into being to catch an attack you know about.

I think there is a spell that lets you turn a spell into a Blocking spell. You have to use it ahead of time, however. Maybe at -10 you'd be allowed to do it in response?

Can it be used on Affliction? I assumed it couldn't be.
