In that case I would have to go back to the Flame Arrow example. They also hit, and still allow reflex saves.
That's a good example, and one I expect most people to emulate. However, I would allow an Arcane Archer who struck someone with an
Imbued Arrow to cause the full damage of the spell without a save. Why?
Because it makes sense, and stretching combat ambiguity just so that EVERY FREAKING ENCOUNTER is one big stalemate between equal leveled opponents is, IMO, lame. I
like the Rock/Paper/Scissors element of a lot of D&D. And we're talking about
one class ability of one Prestige Class, and he still has to roll to hit! Besides, how many Reflex spells are instakills anyway? A high level Deepwood Sniper can easily do the same amount of damage to a single target as a
Fireball.
If the AA is firing arrows imbued with any kind of respectable area-effect spell, then he had to burn a fair number of levels in wizard or sorcerer, drastically reducing his archery effectiveness. And if he's burning Quickened Truestrikes to connect with his Imbued Arrows, then he sure isn't using his spell slots efficiently.
Bottom line, I think its a cool trick, it isn't remotely unbalancing, so in my games, the AA could do it.
