Three questions regarding sacreds.

[Micah]

Most rituals do work on stealthed units with the exception of assassin spells and Seeking Arrow. There might be a few more, but leprosy, murdering winter, the 2 fire remotes, mind hunt (as mentioned) all work. Not sure on wind ride, though that would be quite an effective stealth-breaker.

And Bob, while fires from afar might be good at killing vestals I'd say trading 200g worth of sacreds for 10 fire gems worth of artillery isn't a terrible trade, either...
