User blog comment:Lightsuperior/Making Darius Ult like Zed's Ult/@comment-25003900-20150102150954

I also believe that Zed's ultimate marker is more warranted than one on Darius.

Dariu's ult does flat damage plus AD scaling, plus a percentage increase based on the amount of bleed stacks. So 340 Dmg, let's say you have 100AD for simplicity, you'll obviously have more. 415 dmg that goes up to 830 dmg at 5 stacks. I usually have some form of armor pen, so even if they have armor I'm ignoring a chunk of it. I find that Black Cleaver is a good option for Darius since you have to apply bleed stacks for strong ultimate damage anyway, but that's just me. Should kill anyone with around 700hp unless they're a heavy armored tank. You can play with a smaller margin of error if you'd like, but I tend to keep it safe that way so I don't end up with them walking away having extra HP.

Zed has to factor in his base damage, as much as 50% of the additional damage he's doing, less the damage reduction of armor on the target. If he uses the Shuriken to do further damage as most do, your normal shuriken damage assuming the target is the first hit, which sometimes they aren't, plus mimicked shuriken damage, which is at half, assuming that it's the first target hit, if not it's even further reduced. Zed requires tremendous blind luck, or intimate knowledge of armor values and the amount of reduction in order to not waste the ultimate.

Darius has a lot more simplicity. The only reason I think Cho'Gath gets away with also having the indicator is because it's only able to be used a single time every 80 seconds. Darius can use his continuously so long as it kills.
