Let's Glitch Sarevok Too
You cannot initiate dialogue. Sarevok appears busy.
Silence 15' radius breaks encounters with a talking enemy. So every encounter. Sarevok is silenced, therefore he can't start his "attack my minions" bullshit, and won't himself attack. Silence also causes him to die by 0:38 but it only kicks in at 1:29.
The mage, Semaj, also doesn't actually attack me, it's just pre-scripted spells that trigger when he sees you.
