Hi,
I did a search in this forum without success to find an answer to this basic question: Is flexible formulaic magic virtue can affect the range of a spell like "kiss of death". If yes, if the range becomes "voice" how the Spell can still bear this name?
Yup, it can. Have you never thrown a kiss at someone? 
Name is just that, a name. It does not imply anything. Arc of Fiery Ribbons is not composed of ribbons of flame, or does not need to, at least
Cheers,
Xavi
You've never blown a kiss? :mrgreen:
It is very aristotelician to believe that a good name for a spell will improve its power. 
The name of the spell is essentially irrelevant. You could call it the "touch of death" if you liked, or the "punch of death," and still write the spell so as to require a kiss; or keep the "kiss" name and require a punch. It's nicely-colorful and thematic as-written, however! If boosted to "voice" range, I'd just have the caster make a "blow a kiss" gesture as part of casting.
yeah, thanks for answers 
I thought the lip contact was a necessary condition for the spell to leave, but you convinced me!
There's Necessary Condition as a Flaw, but that's for the magus not the spell.
If you know Potent Magic, you can invent specialized variants that have a "necessary condition". I cannot think of other cases.
You could do the same with magical foci I'd argue.
Also experimentation can give you oddly limited spells
Magi really don't experiment enough these days
That's because their lab totals are already so high
