Hi, I Have read all guide of shadow demon and also the item build for them. but I wanna ask one thing, in all the guide, they all learn shadow poison without dagon as burst damage. how is shadow demon rushing dagon but only learn Disruption and soulcatcher, does that makes shadow demon even more dangerous ? because I thought disruption + soulcatcher + dagon + purge = 100% kill ? is this ok with this build or dagon is just waste of money ?
