During a recent long illness I picked up D3 again for a bit. Got a seasonal hardcore wizard up to para 682 (for now). Extended my survivability with trading DPS for shields (I'd been kinda thinking about the balance wrong). Since the char is hardcore, I favor survivability a bit more. (For example, I have 3 life savers: paladin follower ability, firebird's ability, and passive ability... just in case a lagstorm combines with inattention or something). I'm sitting in T16 for rifts. A bit higher for greater rifts. May do actual pushing later, but I start to get horribly bored when I'm at the point where whether or not I complete the GR in time depends on GR make-up/layout. I have absolutely no interest in hunting for the "right" GRs, even though they have largely improved that. I stick more to bringing chars up to a pretty decent point. You'll never see me in GR 100 let alone 120.
Part of that, though, is the introduction of ethereal weapons to this season. They're absurdly powerful..just look it up if you want to know.
Essentially: Ethereal occulus w/ Power Hungry passive.
Firebirds: helm, off-hand, gloves, feet, legs.
Aughild's: chest, bracers
Belt: Herbrash's Binding (main key: disintegrate cost reduced by 58% - combines beautifully with the cuirass)
Jewelry: convention, SOJ, and a leg amulate (Mara's Kaleidosscope, but that's just because it was the best I've found. Not sure which to aim for).
Shoulders: Mantle of Channeling
Gems: Teaguk 76, Bane of the Trapped 77, Pain enhancer 76% (at some point I may have to switch to Bane of the Stricken.... depends... enhancer helps clearing bosses/trash, and it's a question of how much time I'm spending generating the boss and how much the boss takes).
Cube: RORG, Furnace, Aquila Cuirass (50% damage reduction with primary resource above 90%.
Skills: Blur, Unstable Anomaly, Audacity, Unwavering will.
Between the various skills and arcane power on crit, etc, I'm pretty much always right around 97-100% resource, which means I've got 50% damage reduction from cuirass, another 17% from Blur, a bunch of reduction from elite damage, etc. I got shields going (ie, Energy Armor with prismatic armor). Another 25% reduced damage while channeling. Oh, right, and my weapon reduces damage done by enemies hit by 25% for 5 sec. I can basically stand there and face tank everything, only occasionally having to do a hurried teleport or two (say...my arcane power slips below 90% for some reason or perhaps an elite pack has that detonation on death thing..)
I may try replacing the rings with Focus and Restraint, but I need trifecta or something close. The ones are found are meh. I also have to brush up on how damage bonuses work. With both of Focus and Restraint's bonus going, I should be another +100% damage. But is that additive or multiplicative?
Meanwhile, my SOJ has 20% fire skills and 25% to elites; convention is 200% damage to elements on rotation, and while I'm just about always using fire (firebird's disintegrate w/ the one fire version of the skill going), that 200% comes around a couple times at least on the GR boss and speeds things up.
I did start a few others I want to play around with.. barb, monk, witch doctor. I especially want to try this build that goes around items and gems that combine to massively increase bonuses from legendaries provided you have no set items. That's one thing that always drives me away from D3....sets. **** sets. I hope there aren't any in D4.
But how do people get to like...GR120, 130? How? The math obviously has to work. I suppose if you are attentive enough and lag-free enough to never get hit....
