Lightning Overload Stormcaller is a single-mastery Storm build for Level 22 focusing on Lightning Call's incredible ability to land ranged-AoE Lightning damage paired with the Overload effect to destroy mobs beyond distance and damage bosses before they attack while maintaining mobility and survivability.

This build is reliant on your capability to micromanage your health, barrier activation and positioning, which can be detrimental to some players' experience. You are also reliant on energy regeneration affixes for the most part as Lightning Call and the stored energy requirement for Storm Nimbus causes your energy pool to whittle down quickly.

The stats shown above is a general reference of what you want to go for when building your character.

Preferably, you will want to solve your character's energy issues to be able to commit to multiple Lightning Calls via Energy Regeneration while also increasing your survivability by investing in some Energy Barrier and Vigor modifiers for your equipment.

You are also advised to stack up on Lightning Damage, Knowledge and Spell Damage to increase your raw damage against enemies. Follow the stat order below to make the build efficient!

  1. Energy Regeneration
  2. Energy
  3. Knowledge
  4. Increased Lightning Damage
  5. Increased Spell Damage
  6. Elemental Resistances
  7. Energy Barrier
  8. Vigor

Note: These stats are randomly-generated, so you can keep farming for weapons to build your character properly.

There are currently only two Unique 2H Staves in-game and the most compatible for the build is Thyrsus, which provides you with extra Energy Regeneration and Energy Barrier. Thrysus will require Knowledge as the main stat requirement. This weapon will primarily serve as a stat stick for this build.

Alternatively, the more fitting weapon for this build is Katharsis, which improves all of the stats needed in the build. However, you may have to invest slowly on Agility for later levels as the stat priority for this weapon contradicts with the priority stat investment you'll need.

The core of this build is focused on Call Lightning and Overcharge, a passive that provides a dramatic damage increase to active skills with their Overload modifier enabled at the cost of burning some health. Directly benefiting this is investment in Storm Nimbus and Thunderstorm, which provides a sustained aura that magnifies Lightning damage at the cost of reserving some energy.

To counter these, focus on passives such as Arcane Influx with the Energy modifiers and Storm Nimbus' Conservation to mitigate energy loss. Upgrade Barrier and Storm Adaptation to tank enemy hits and be resistant enough to the self-damage effects of Overload stacks.

Finally, to boost your mobility, equip Blink with the Repeat and Thunderstorm modifer to allow yourself to deal damage while moving across the map and allow you to reposition properly especially against bosses.

List of All Skills

Attribute Priority

Attribute Prioritization
Knowledge ▶ Vigor

Focus on getting your Lightning Damage up by investing on Knowledge first and foremost which also allows you to equip Staffs to improve elemental stats even more.

You can then focus on Vigor to keep yourself at a decent health to tank your Overload self-damage and improve your Resistances. We recommend a 1:2 ratio for these two stats, with 1 Vigor for every 2 Knowledge being a good balance.

Playstyle and Skill Rotation

The Lightning Overload Stormcaller build uses a simple play rotation, primarily requiring you to only keep your Storm Nimbus active at all times and pressing one skill, Lightning Call a few paces ahead of the enemy to hit them properly.

The micromanagement part requires you to use your Barrier key to mitigate enemy attacks and self-damage while using Blink and Dash to reposition yourself whenever swarmed. Using energy and health potions in between is also crucial. The rotation is as follows:

  1. Activate Storm Nimbus, no need to turn it off again unless it does so, in which case, turn it on again.
  2. Use your Call Lightning at a distance from the enemy. Make sure to pre-fire the skill close and not on the exact position of the enemy to avoid misses.
  3. Should you need to tank hits or reposition, activate your Barrier or use Blink and Dash to hold your ground and keep on attacking or move to check your health or energy.
  4. Use your Health and Energy potions whenever needed.
