Collaborative Thaumaturgy - does it work if used as a readied action?


Rules Questions


The spell.

I was thinking of ways to utilise this, and considered the option of putting it into a spell-storing ioun stone, then having cast it from the ioun stone when, say, I want my Overland Flight spell extended. Not necessarily the best use of the spell slot, but this is as an example.

I realise that the casting time would increase to a standard action if the spell is cast from an ioun stone. Would this stop the spell from affecting my other spell if my familiar readies an action to activate the ioun stone?


I can't see why it wouldn't work. If your familiar uses the stone you aren't casting it on yourself, which looks to be the only restriction. If you are using a readied action the standard action casting time is irrelevant.

But..

I could see this being ruled against you as well, especially if your GM thought it was 'cheesy'. There's not really a precedent in the rules either way because immediate actions are never compared to readied actions so we have no idea how they interact.


I don't think it's particuarly cheesy, in light of the comparable cost of a metamagic extend rod or third level pearl of power. The versatility is a plus, but you pay for it through the cost of the ioun stone (or ring of spell-storing).

Other minds may disagree though.

There is nothing whatsoever that would invalidate a readied action casting of this spell. A readied action interrupts the action it responds too, just like an immediate action.

Go for it.


I also don't think it is cheesy, and totally agree with you that it seems legit... but I can imagine an oppositional GM would try to poke holes in it, as I said. I think he'd be wrong for trying to poking holes in it, but it's always good to mention in case of future disappointment.
