While playing my other Seasonal characters, I "accidentally" managed to acquire three different Crusader items with boosts to Blessed Hammer. Two Flails and a Shield; I don't remember their names. One makes them faster, one makes them do more damage, stuff like that. Anyway, it occurred to me that I've never done a Hammerdin in D3 (partly because they're not Paladins anymore, so I'm not sure what you call them), so I decided that even though Crusaders aren't my favorite D3 character, I'd try a "Hammersader".
With three Gems of Ease now to help out with levelling, she hit 70 pretty quickly, and was soon grinding for gear. Yet another Flail dropped, this time it makes your Blessed Hammers bigger. I had to start cubing some of these, and got the Achievement for cubing x powers. I don't even know what the number is, since I didn't really look that closely, having decided not to bother with Guardian. But okay, now I'm 5/6 of the way to Guardian. I guess I really need to reconsider Boss Mode. It will bug me forever if I don't do it and leave it at 5/6 done. (Apparently I was okay with leaving it 4/6 done, but 5/6 is not acceptable. I'll always know that I could've just done "one more thing" and gotten it.)
Not asking for advice, although it's certainly welcome. I'm assuming the faster character would be the best one to do it; in this case the Gears Demon Hunter because of the insane speed you get from Momentum, or maybe the Tempest Rush Monk. There's some combination that cranks your Sweeping Wind up to 13 stacks and adds 5% movement speed per stack, so she really flies.
I'll probably make a list, just to organize which bosses are in which acts, in order to jump as quickly as possible from one to another. Then off we go. This could be interesting.
But first I need to finish my Hammersader.
