Re: the OOC thread II
I take your point, but the caster level of a spell is, I believe, determined at the time of preparation, not casting. So, yes, a scroll can be prepared with a higher CL - but it will cost more. Whereas the decision of whether to include the companion in the spell's effect seems more akin to a targeting choice - just like you can specify where the scroll-cast fireball should go, or whether your scroll-cast magic circle against evil is directed inward or outward - these are simply questions of targeting/application that are selected at the point of use.
But, like I said, I do see your side of the argument as well.
Was there a particular buff in Sandstorm that you were thinking of? I looked at the spell lists there but didn't see anything that jumped out at me. (And, for thematic reasons, I was looking much more closely at Frostburn and Stormwrack when designing Isigar's spell list and equipment...)
