Metamagic feat: Rune Spell

[Jeph]

Rune Spell (Metamagic)
You may transform your spells into trigerable symbols.
Benefit: Only spells with a casting time of either one action or a full round action may be affected by Rune Spell. The casting time of the spell increases to 10 minutes, and the duration changes to "one year or until triggered, and then (original spell duration)." For instance, a Rune Summon Monster 3 would have a duration of "one year or until triggered, and then one round per level." In addition, the caster sets trigger conditions when they cast the spell, as per the spell Glyph of Warding. A Rune Spell takes up a spell slot one level higher than normal.

Thoughts?

It does pretty much invalidate the whole FRCS Rune Magic section Also, what would stop a cleric from casting 1,000,000 Cure Light Wound spells in advance and bringing them with him (casting his spell on tiny boxes, for example)?

It's not just good. It's not just broken good. It's mind-bogglingly, world-shatteringly good.

Any third level cleric with this feat can now (effectively) create potions of Cure Light Wounds for free.

Every wizard everywhere would take this feat, buy an extra spellbook and inscribe a rune on each page, effectively letting them scribe an unlimited number of scrolls for free.

To be balanced at LA+1 it needs to require a costly material component on the order of (modified) SL*CL*25gp (similar to a scroll). Even then it might still be too good.

Hmm.

I'm beginning to think it would actually be best as an Item Creation feat, "Scribe Rune" or somesuch. Costs would probably be the same as a potion...

 

[Scion]

Perhaps if it had an ongoing cost. You start off needing one slot level higher, it takes a long time to cast, and then for everyday thereafter that it isnt triggered you have to leave a slot of one level lower empty to keep the rune 'charged'. ie if you had a 2nd level spell, cast it the first day at 3rd level, and then from the next day on until it is triggered you have to keep a 1st level slot unused (or drained as if it had been cast).

 

[Graf]

The SL books have rules for runes (Burok Torn I think). As do numerious other game systems.

Not to be a pain in the butt but what is your goal? If you have an image of the kind of function you want runes to be in the world it'll help make a rule that makes sense.

Or you could just thing about how you want them to be different from scrolls and potions and work from there.

 

[Strigo]

Couldn't you say that you cannot use that spell slot until the spell is triggered or aborted? Then you stop people from making 1,000,000 CLW runes?

(If you want the thing to be even less dangerous, you could make it impossible to 'abort' the spell without triggering it. If you cast a spell in runeform, you must trigger the spell. This means you don't want to lose the rune, and you have to let go of a potentially dangerous spell, maybe. This causes trouble for the spellcaster, I think.)
