Expense is no issue for me. My fcr is needlessly 140% with my only replaceable piece being my magefists. I could swap them out with some chancies but that's really the only thing. I'm not sure how you're achieving 37k lightning damage. Right now I'm clearing in around 3 minutes, slightly over, so I don't really see the point in pushing it. My lightning damage as of last check was 29k however, so I'm feeling alright. If you have a better setup I'd like to know what it is. Pretty much my space for improvement looks to be 2 more light skillers, which I have as open space now in my inventory.
Setup:
Eschutas
Spirit
Griffons
CoH
Maras
SoJ
Another ring - (no second SoJ, open to suggestions here - wearing Dwarf star for fire absorb currently, just for ease of runs - could wear wisp projector for light absorb from gloams but they're not really an issue I've had)
tri res fhr frw boots (seriously a sick pair, could sub for wartravs honestly, but dont care enough about mf to do so on baal runs)
arachs
Magefists - seriously serving absolutely no purpose right now. Frostburns would mean less mana potions - trangs would mean more resists which I don't need - chancies would mean more mf which I don't care about.
switch is spirit and CtA with 6 bo
I have 6 light skillers, cube/id/tp/life+mana charms for the bottom row. Two open 3columns to the left hand side where two more light skillers could go.
Honestly, maybe my lack of light damage could be attributed to the only being level 93 (I dunno why I though I was 94, my mfer is 94 just from pindle) - but the runs are super duper quick. Everything dies within 5s of being casted by baal. I static 4-5 times and chain light/light to finish off stragglers. goes quick. Even last wave, very quick, comparable to other videos I've seen.
I could probably drop some resists but I don't know how that would help my damage. My eschutas fares better than my hoto as far as damage and I am still at max resists on everything. I could sub my CoH for vipermagifacet and then drop my spirit shield for something that would make my runs easier, like phoenix for the redemption. But I'm not into using pre1.13 items so I don't really see much room for improvement aside from two lightning skillers. I could snag a better crafted amulet (2sorc fcr any resists) and drop maras, and then I would maybe be able to get rid of CoH and Spirit but... I dunno where the extra damage you're getting comes from.
Also my life is under 2k currently by a smidge. I could have better lightning skillers with more +life, but I'm literally at the least possible str and the rest in vit. Dunno if spirit monarch is really the issue here - I feel like it could be better overall.
As for the merc - I don't even know what to say. It's probably a skill issue. When I have a good run there's no issue. When I have a bad run he dies, either to hydra or to listers boys when lister is LI and enchanted. I feel like this is a skill issue on my end, not quite getting the positioning right. It's definitely something I'm working on.
However, what I can't see is subbing out my treachery for duriels. I just absolutely cannot see this as being good for my run overall. I think it will KILL my mercs survivability. I have tried it before, it might be because he's only 93 (this is laughable, but whatever, I'm playing other games and I've only just started). It seems whenever I swap out treachery he just gets smoked. I have an eth upped shaftstop that I've tried to sub in every now and then and he still just doesn't quite survive the same way. I haven't tried fortitude. I don't have a vamp gaze, although I'd love to have one so I could try that instead of andys. Right now, I'm locked into using andys and treachery because there's no other option. The poison is a mere annoyance. It dictates that I must carry the antidotes and that's all. I would say this slows down my run time by about 5s because I have to pick up more antidotes every 3rd run or so.
To sum it up - I think I just have to get going. I think the main issue now is skill and willingness to just let the small things slide. I want my runs to be perfect but I don't think they can be now. In practice, the difference between a good and bad run is 3:00 to 3:30, which is still great run times, better than many of the 99ers that have come before me, excluding the really megafast megaawesome epic people. Even if the merc dies (I would say he's dying 1/20 runs right now) thats only adding about 30s onto my run time every 20th run. So that's really not a big deal. I feel like I just have to grit my teeth and bear it, because swapping out for duriels just isn't a viable option just to avoid poison. I feel it will be easier in a couple levels. Merc resists are maxed out so only really poison length reduction could benefit him but I think it'd add more time to get it if I'm going to lose the fade proc..
@corrupted - I can't imagine a gear setup that allowed you to achieve that mf with that dps - perhaps you could post it for me so I could be enlightened. I'm not going for the 200 FCR because that will never be a quicker runner for me. Also if you could name the expensive things i'm missing for my merc, I'd love to hear it because you didn't really name any, and I'm about out of options with trying to think of alternatives. There's nothing too lucrative, I'm a fantastic runner and I've put up thousands on thousands of runs to get things before. Treachery just seems like the best option, I've seen comparisons to everything in strictly mathematical terms, including ebugged forts which fare worse overall in damage mitigation in almost any situation by comparison to fade.
Anyways, sorry for the wall of text. What I'm saying is - take a look at my setup. Take those items, consider any amount of ridiculous wealth or whatever, and tell me what could be better. I can do it, I will do it, it's not a problem. I just can't see it.
