Just killed normal diablo now though, lol that's simply impossible with a spearzon. I'm using jab exclusively. Just actually found bloodthief on my way there, which i've been trying to trade for. That's freak luck, lol. Used a pike with a lot of damage, but slow with jab, so that was out of the question to use that on diablo. With bloodthief i thought i'd be able to run in, get in a jab and run out again, after he'd used his lightning attack. But it was too dangerous and tedious.
So i had to revert to bow and arrows, with no bowskills ^^ took forever. Tried switching to bloodthief mid-flight to try to trigger bleeding, which did work from time to time, but seemed to just divert focus and waste time. I read up that ut did about 200 damage over 8 seconds, and with diablo having 13800 hit points, it wouldn't make too big a difference.
Now it's off to act 5. Going to test the pike and bloodthief to see which is most effective. It is safer to be able to run out quickly when jabbing, but doing less damage is also counterproductive. So we'll see.
