Hm... Just a thought. Addle then saboteur and slow2 5/5 on it. How far can the mob's recast timer be taken down? Is it even a known variable? This really needs to be tested. As stats so far shown on certain threads posted, being saboteur is supposedly double length and potency. And even more with your mnd potency gear how much could you drive it up?
(Granted I'm using hypothetically if you aren't resisted)
