Woah yeah, Oblivion Staff/Orchid is exactly what I need for mid-game. Eul's/Sheepstick are cool for that added disable. I tried Force Staff once but I couldn't get the hang of using it well. I imagine you can save yourself or even pull an enemy hero away from his team if you know how to use it. If I'm going the support route then I love getting the Urn of Shadows as well for healz.
Diffusal Blade looks really good and if I ever play against that Sorcerer or Summoner or whatever I'll go for that, because I hate his demon golem thing. Too much agility though.
But yeah I spam Powershot to harass, not on creeps. Doesn't really matter when your lane buddy is autoattacking though : /
I guess Phase Boots are a nice option, too. I usually go for the Strength Treads on all characters just because it lets me live that much longer, but I should try switching it up.
