That's a cool trick. More time with Minthara, one of my favourites.
Regarding Silence, I used it to aggro Moonrise defenders in 1's and 2's and systematically wipe the place clear. Bonus, as a Concentration Ritual, it doesn't cost a slot and activates the weird ring that does +d4 psychic damage while concentrating.
It's a really good spell, still using it end of Act 3.
