S10 StormWeaver - StormCloud - Stormbolt - Lightning Surge

01 Overview #

StormWeaver in Season 10 is still easily one of the best casters with some of the most robust kits available. Having a teleport is still a good mobility advantage and being able to seamlessly transition between different builds and have variable options is great. StormCloud and Stormbolt make for an easy experience in the early and mid game while Lightning Surge still remains to be a potential powerhouse late game with high-end items. Either build is viable and totally possible to take to the highest parts of the game.

The mobility hit does feel bad but I still think StormWeaver is strong. We did here mention that there are Light Radius nodes potentially used for Magic Caster scaling that could be, in theory, very good. It's going to be challenging to push it as high as we used to when it was stronger with Lightning Surge constantly proccing small StormClouds under things. You can place StormCloud/Stormbolt pretty high up into the game with the correct gear and enough skill, haste, and AoE damage stacking.

The Good

Still a very powerful caster damage wise
Versatile build options
New options available potentially with charged bolt
Stormcloud & Stormbolt untouched
Still an extremely strong caster
Light radius nodes?

The Bad

Lightning surge nerfed
Charged bolt base nerfed
Teleport nerfed hard to a charge system
Top-end caster FCR and Skill Haste has diminishing returns
No built in defenses

02 Season Changes #

Lightning Surge will be doing less damage with Chain Lightning now being an 18% proc instead of 100% This means it is a bit less clear, though, with how many targets it hits. It should still go off fairly often. It did receive a 0.5% upgrade in damage per point but that's probably not enough to offset the loss. Pulsing Charge got a massive buff though it did get a proc chance. However given the damage increase a god. I think it will actually do more damage even with the proc chance. However Charge Bolts and the electric field Nova augment did get a damage reduction as well, which is a weird choice considering they just buffed what might make Charge Bolts good. We'll have to actually see in season if charge bolts can compete with other forms of damage.

Also the teleport nerf obviously hurts our mobility significantly so we'll have to work around that by gaining more movement speed for when we're out of teleport charges as we will most likely run out of them quickly once we get high cast speed. Overall however, StormCloud and Stormbolt seem untouched, meaning our mid and early power is still the same, an absolute monster. Our late game power is yet to be seen but should be still viable enough.

03 Loot Filters #

Loot filters are definitely something that you should utilize whenever you're leveling up a new character. I have built filters that I personally use myself to ensure that I have a smooth journey through the campaign.
What I'll offer below is a low-level filter and then a generic trade filter that I use at the higher end. Please be aware that the trade filter will hide many things and is mostly a high-end filter, one designed for people that kind of know what they're doing or what they're getting into. It is not usually for the general public but it is highly requested.
I do suggest that you learn to make your own filter. That way you can understand if you want to make modifications to mine, you are free and capable to do so. Everyone's preferences for these kinds of things are different and I am not 100% an expert on anything.

05 Leveling 1–100 #

Charge bolts are just flat out the easiest thing to level with and there's really not an ideal alternative. Storm bolt just isn't as simple and straightforward and every five levels we gain three more projectiles to charge bolts, giving us better coverage. Pulsing Charge is an immediate pick up at level 8.

06 Level 100+ Skill Trees #

This is probably the most effective early level 100 farming build. It easily clears pretty much all early content with little to no gear needed and is massively buffed as you get more points in the incarnation tree. It usually can handle most bosses but when you are low gear I suggest switching to the StormCloud single target tree for even more damage as bosses have a lot of health in hell when you don't have gear.

08 Gear #

Gear is something that is always a suggestion though there is always going to be a meta and a best item. However I will try to include alternatives below the gear section for you to equip or try if you cannot afford or cannot find the main ones that are listed on the inventory.

This is the kind of gear you want to be looking for when you are first finishing the campaign and starting to step towards nightmare and hell farming. This is your "I'm pushing towards hell difficulty" kind of gear. Most of these items should be relatively easy to find and there are many runeword alternatives. However I do not like to always include runewords in the actual inventory and will only include them as alternatives as I do not think they are a guaranteed thing. While they may be easier to farm at times, I prefer this methodology of showing you what the ideal satanic items are. The flasks and relics will remain the same. Obviously you will not have them maxed out or have these flasks right away. These are the flasks that you are going to be aiming for all the way towards the super late game when you replace them with some much rarer more expensive ones. The relics are also something that you can swap in and out this season so feel free to experiment with things that you like more than this.

This is an alternative Aura and MF hybrid for farming while also increasing damage and survivability using Crown of Doom and Pearlescence for extra magic damage.
