Is it an epic-level template?
Would said epic-level spell be affected by the non-epic Spell Turning
I don't think it's an epic template, so I'd assume that the only epic-level spells that would be affected would be those that Spell Turning
would affect. Which, in general, would probably not be that many, but I suppose some Wizard somewhere might create a 60th level Polar Ray
for whatever reason.
