1. Can curse of tounges slow down hunters aimed and steady shots
2. Are hunters vulnerable to silence?
Hunters are SEMI-Vulnerable to silence. Some of our spells/skills won't work while silenced, but others will.
As far as Curse of Tongues slowing down our Steady/Aimed shots...I'm not sure. Easy thing to test, though. Set up a mock-duel.
Never studied the issue, but I would assume, from the powers that promote sanity, that CoTounges would not impare a hunter's aimed/steady shots.......Not unless they threw in something silly like having to humm the jingle music from Jepordy while activating it. :D
