Hello again, fellas! 
Druid class is usually pretty interesting and unique in games. Be it a conjurer of destructive elemental forces, beast tamer or shapeshifter - lots of fun is guaranteed if you pick the class (the last is especially likeable for me). For example, Diablo 2 LoD. Even though I have never beat the game on Hell difficulty, most of my characters were Druids because of the possibilities they have. Yeah, those were good times 
. But in GD…
“Destructive elemental forces” became Cold/Lightning Trozan with worst RR possible (Ultos is better on Warders, in my opinion), “beast tamer” is much sensible on other classes and “shapeshifter” was not even an option 
. Bad sustain, the worst RR, no DR, everything in this implementation of Druid class seems awkward and not pleasant to play. I made only one Druid in GD and threw one build idea after another. One of the last one was Aether Upheaval Veilkeeper + Temporal Arcblade that was… just doing some basic stuff, not bad, but not good either. So I scrapped it. But before removing components and gear stuff I decided to try Lightning variation of Upheaval. Not much expecting from the idea. How did it turn out?
The answer is below.
1. Grimtools link.
High-crit high-OA Upheaval setup with Storm Totems mixed. The devotion tree is, let us just say, “for everything’s practical use”. This is why we have Imp (half-converted to Lightning), Watcher, Viper instead of usual Korvaak, Ultos and Tempest. And Giant, since set we use supports Health regen nicely. The damage of my setup may not be the highest possible but still enough not to fall asleep (or knocked out by enemies 
). Lucky several Upheaval strikes can obliterate even Nemeses in seconds and it is wonderful to watch. Physique dump is because our DA and Health are already not that high (thanks to Heart of the Wild nerfs).
2. In-game character stats.
general stats, only passive buffs are active. Damage Per Second is for Savagery
magic stats
defense stats
3. Gear/Build explanation.
For enabling Upheaval builds you need a lot of OA and %Crit Damage. Both masteries provide much of it and gear I chose complements those stats. But it is very important not to forget about other stats too - Health, DA, %AS, overall skillpoints and so on.
- Core items.
Set. Veilkeeper. Nice heavy Aether/Lightning set with Health regen flavor, with bonuses to Upheaval - flat values, %WD, some Stun - and Arcane Will/IEE - huge OA, duration, %AS, even some %Phys res (unlike its brothers Ember and Goredrinker). Great set overall.
Weapon. Stormreaver. Big Lightning axe with +2 to Shaman, big OA, bonuses to Storm Totem (wish we can summon not 1, but 4 totems at once
) and flat damage values to Savagery. Mostly Electrocute-oriented, but for our purpose works fine. Craftable. - Mandatory items.
Amulet. Peerless Eye of Beronath. Great amulet slot with +1 to All Skills, OA/DA, %Crit Damage, Health, triple resistances - eveything you need. I do not use its granted skill, wish it was a proc.
Rings. Glyph of the Storm Witch. +2 to Storm Totem, Aether-to-Lightning conversion, OA, %Pierce res, proc is okay. Mostly taken for OA and conversion (useful for Upheaval, Savagery and devotions).
Pants. Stormcage Legguards. Decent Lightning pants with OA/DA, +2 to Raging Tempest and Maelstorm, proc is like on rings but works on hit.
Relic. Eye of the Storm. An amazing Shaman relic with tons of flat and %Lightning Damage, Spirit, %AS/%CS, with granted aura.
Belt. Storm Shepherd. +1 to Shaman, Aether-to-Lightning conversion (important), even some OA and %AS/%CS, needed %Vitality and %Chaos resistances.
Gloves. Plaguegard Grips. Craftable slot with in-built %AS, %Phys and %Bleed res. Look for OA and %AS. - Can be changed.
Boots. Wyrmscale Footguards. Nice Fire/Lightning slot with OA/DA, +2 to Storm Totem, %Petrify res and defensive proc against Elemental/Bleeding. Good-rolled Stoneplate Greaves, for example, can be better.
Craft with whatever bonuses you want. I have some meager ones like Energy regen and DA.
About Resistance Reduction. Total amount is ~97% (-38% from Raging Tempest modifier of Wind Devil, -35% from Widow constellation and flat 24 from Revenant constellation) plus 20% from Viper constellation, so it may vary. As usual, Grava, Maiden and Morgoneth are pretty resistant to our attacks (first one also fumbles us much, second deals heavy Physical Damage, third one is just annoying to beat). For other bosses and Nemeses - heavy Physical fighters and casters with shotgun attacks hurt much, our DR is not great and consistent. Still this Druid perseveres and crushes .
4. Gameplay.
Uptime Wind Devils and Storm Totems, obliterate with Savagery + Upheaval procs. Mirror/Wendigo Totem/Nullification in hard situations, Rahn’s Might for movement. Sounds simple? Well, yes and no. Wind Devils are awful and have stupid behaviour, Totems have short range and short lives. So do not expect an easy cakewalk and practice! 
5. Videos.
Mad Queen (nullify her aura).
Kra’Vall.
Lokarr.
Morgoneth.
SR 75 full.
Avatar of Mogdrogen (old video) (potions are in the video, no Aether Clusters, one healpot on second phase because I am a casual that does not play well 
)
Callagadra (potions are in the video, no Aether Clusters, occasional healpots, kiting - the build cannot handle big Physical blows well).
Crate boss (potions are in the video, one Aether Cluster and occasional healpots. Pretty annoying for its disengage jumps and boxes (as usual), with right position can be killed faster through Mirror+Aether Cluster rotation 
).
Clones of Bourbon (potions are in the video, no Aether Clusters and healpots).
Barrowholm hates me, so they did not let me beat their patron Ravager .
So, that was my Veilkeeper Stormreaver Druid. Much better than expected, but I prefer more comfy QoL and tanky characters still. Druids in GD must be played smart to show great results, this is what I have learned. Worth giving a try.
Thanks for visiting my topic. Until next time!
