Valdaran debuff dont ignore overcap resist, his lightning nova is actually the same spell as Mogdrogen in a weaker version.
You are right about other boss that you mentioned (Sentinel, Anastaria, Shar’zul) and have absolute debuff where overcap wont help you.
I learned something new today it seems…
I thought that additional resists were literally wasted when the resist gauge said 80%. So meaning that if I had 120% resist combined, I actually have 40% more to counter a debuff even if the tooltip wouldn’t go past 80% ?
He can be kitted around with a good ranged weapon. Only really need to watch outr for the exploding crystals and get close once you break free from his entrapment.
Was shadow striking and shooting him with rifles while running around for a reasonably easy time.
Nice to know that I can overcap Valdaran so he doesn’t gimp my resists too much 
Sorry, but I’m not wrong. Valdaran’s Lightning Bolt will ignore overcapped resistances. Test it for yourself if you don’t believe me.
Just tested it, you are right.
I even thought it was another spell animation applying his debuff. o.o
Kind of unfortunate, but I guess that’s what reduced stun resists are for…and not trying to facetank him for the most part.
On a seperate note, I’m making good progress. Should be almost done with Hardcore Elite.
If all goes well, I’ll be able to finally farm for legendaries in Ultimate by running Cronley’s and Kymon’s Chosen (Both are still at ‘Despised’ so I can really go to town on them in Ultimate)
Is it feasible to obtain legendaries this way by opening chests/killing heroes though? Or should I just go ahead and start getting a Nemesis out?
Finished softcore Veteran with pretty similar Spellbreaker build. Only 2 deaths, but going hardcore or against nemesis with it is complete suicide, I had to name my character 'Squishmeister", one wrong move and you’re dead, but damage of this build is insane if you’re in the good spot.
Which is why I’m so damn careful about how much hostile reputation I rack up.
if you ask me, only 3 out of the 6 in-game nemesis enemies are perfectly viable for hardcore play.
The 3 are Aetherial, Cthonian and Undead. All you got to do is watch some YouTube Vids to learn their patterns and do the necessary preparations before fighting them.
The other 3 which comes from Cronley’s, Kymon’s and Death’s Vigil are way too risky for a spellbreaker. Fighting them is essentially like a game of Russian Roulette on Hardcore.
Coincidentally, they are also the easiest to find and the hardest to bring up to Nemesis status at the same time; so I suppose if you manage to piss them off enough, their nemesis hero will end you faster than how a blademaster clears mobs on Ultimate hardcore.
Then again, I really do my best to avoid certain places on Ultimate mode, so it’s all a matter of picking your battles or not fighting until you are all pimped out in purple 
So Valdaran debuff is absolute. Guess i was wrong. But i could have sworn my electric resist didn’t changed when he debuffed me. Then again, i fight him at melee or near melee range nearly all the time, so he doesn’t debuff me that often since he only uses it at a range.
I fought Fabius maybe 20 times or so. His damage can be unpredictable. Sometimes he lightly taps you and other times removes a third of your health. It’s specially more annoying when he spawns with some nasty shoulderguards, like ones giving him extra pierce, bleed damage and OA.
The only Nemesis i haven’t fought yet is Iron Maiden.
This Basically. I’m guessing that damage is more than enough to one-shot even the tankiest character…unless you try to one shot him first.
Also, I never fought the Iron Maiden Nemesis too, but I can bet it’ll be like the Kymon hero you fight at Fort Haron- She’ll rush you down and smack your brains in while you are stunned…just with a lot more health
Iron Maiden is even more dangerous than Fabius. She has cadence, fighting spirit, blitz and forcewave, combined with chance to spawn with nasty weapons (most stupid so far for me was a plaguebearer sword with some suffix i forgot).
Physical, bleed and fire resist (for burn) need to be capped to beat her.
Don’t forget that she has Menhir’s Will too. Serious PITA.
I already avoid Nathaniel and his friends (From the ‘Burn The Witch’ sidequest located in ‘The Blood Grove’) on Elite and beyond.
I almost nearly got my own ass handed to me by 3 Homestead citizens no less, so I wouldn’t even want to share the same zone with an overzealous Blade Maiden Nemesis with mostly Soldier skills…
So consensus is that Moose is considered one of the easier Nemesis bosses? Not too happy to hear that, since I went looking for him on my pet Conjurer just now and his second form evaporated them in seconds. At least his locations are easy to avoid.
Pets can take ol’ Bloomoo, but you have to buff their cold resists, obviously, and micromanage a bit. Taking out the crystals whenever he summons them helps a lot.
I think that much depends on the build you are using: no nemesis boss is always the “strongest” or the “weakest” in every situation. I dealt with Moose with various characters and with some of them is a real PITA (mostly with melee DPS oriented chars). Besides the cold damage, it deals a lot of physical damage and the stones he spams, with their freeze effect, are very annoying, you need some decent AOE for them.
Moose and Benn are often considered easier because they are much slower than Fabius or the Maiden, which is making them easier to fight against if you have some DOT damage or some ranged attack.
I’m sure once the build is more complete (which will take some RNG for drops, but what doesn’t in this game), he won’t be a problem. I just mean if he’s capable of turning a maxed out Briarthorn with two different life buffs on it into a bundle of twigs that easily, I don’t think I want to meet any of them on Hardcore.
This essentially.
Not that I don’t like the challenge, but I really see a lot of problems and issues since the game seems to be awfully picky about how builds go about with Nemesis enemies.
Nevertheless, I am fine with this, given that 3 of them are quite viable (In all honesty, Moose is an example of why shouldn’t you go full on single-elemental: Because of him, I essentially made my Cold Spellbreaker do Poison/Elemental damage with his Shadow Strikes and max out at least 1 constellation for elemental and poison each)
And in all fairness, the 3 who can legitimately wipe you out is hard as balls to grind rep for. I think it’s an ingenious way to punish players like me who over-grinded and treated Grim Dawn like a typical rpg.
I learned a very harsh lesson from my first defeat on Ultimate and knew that it should be normal for me to fight guys 4-5 levels above me. My overgrinding caused 3 Nemesis to pop up at random when I was still level 70-ish on Ultimate Hardcore and I had none of my class-specific purples. I guess either way I screwed myself hard at that point.
And on the topic of acquiring end game Legendaries…
Which is more viable/suited for Ultimate Hardcore?
Heroes & chests or Nemesis hunting?
I have searched and searched, but all the threads are based on Nemesis hunting with a strong implication that it’s being done on Softcore.
For me…I actually plan to keep hostilities with the Cronley faction low…then hit them hard on Ultimate Hardcore for my grind to Level 85 and potentially take advantage of the bonus to legendary drops (Cronley has about a handful of heroes…more than that if you go into the mines and within the Four Hills).
I’ll just stop short of Nemesis status and perhaps go through Royal Hives or the Pine Barrens region if I need anymore Legendaries.
