yep
after a while my rule of thumb became, don't use that tornado invocation in any fight with high-level kith wizards or fampyrs. they will use spell reflection, and even if the battlefield looks clear at the moment, the invocation bounces so slowly, they'll probably pop it up while it's in flight.
i think Her Tears are area effects, technically, instead of projectiles. e.g. like rolling flame instead of necrotic lance.
though this reminds me of the most ignominious party wipe i've ever done. empowered Her Tears, split-second before the invocation casting completed my skald got confused (don't remember, but i think it was one of those high level shadow-type creatures that can do that). of course my party was clustered next to each other, that was a ton of damage in an instant that instantly wiped out everyone (incl chanter from the smaller additional shards upon impact) and killed Vela, to boot. never had a fight go so quickly from "absolutely winning" to "instant loss" so quickly.
