Blood Mage Lightning Warp Endgame Build

Introduction

The Infinite Lightning Warp Blood Mage Witch is an insane speed-farming build, capable of destroying entire screens of enemies while flying through maps. Lightning Warp teleports you to Ball Lightning projectiles and enemies in culling range. Cast on Critical triggers Arc and additional Ball Lightning projectiles to create a gameplay loop of infinite Lightning Warps. Lighting Warps and Arcs deal devastating damage, capable of deleting Max difficulty pinnacle bosses in seconds without needing any skill swaps.

Regarding survivability, the Lightning Warp Blood Mage features extremely high life and energy shield recovery, making the build nearly immortal.

This build guide assumes you have reached endgame maps around Level 65. If you have not yet completed the campaign, follow the Frostbolt Cold Snap Leveling Build Guide. For an endgame build that starts with more damage on a low budget, use the Ice Nova Comet Endgame Build Guide.

Build Mechanics

Infinite “Mana”

Mana is a primary concern for the typical spellcaster. The Mana costs of Skills continue to grow as you increase skill gem levels, and most support gems multiply costs even further. To achieve enough Mana sustain for these high costs, a considerable investment must be made to gain Maximum Mana and Mana Regen using Skill Points and gear affixes.

The Blood Mage Ascendance node, Vitality Siphon, enables Spell damage to be leeched as Life to provide an endless source of Life sustain. This enables the Blood Mage to utilize Blood Magic, removing mana entirely to only pay skill costs with Life.

Life leech by default occurs over 1 second, but Atziri’s Acuity grants instant leech from Critical Hits. This effect is crucial for keeping your Life pool full, especially during boss fights. Without these gloves, your Life pool may not recover fast enough to keep up with the rate of triggered spells, causing you to lose casts.

Life is also recovered by Life Remnants, granted by Sanguimancy. These life globes spawn primarily from killing enemies and can overflow Maximum Life to 1.5 times the normal amount. Continue to absorb Life Remnants while clearing groups of enemies to become nearly invincible.

Survivability

The Blood Mage ascendancy nodes, Grasping Wounds and Crimson Power, significantly boost survivability. Equip a Chest Armor with up to 1,000 Energy Shield to gain 1,000 Maximum Life.

Once Rathpith Globe is obtained, the highly stacked Maximum Life also scales Critical Hit Chance and Spell Damage. Spells that reach 100% Critical Hit Chance are effective for instant leech when combined with Atziri’s Acuity.

In addition to the instant Life Leech, an insane amount of Life Regeneration Rate is granted by Sacrifice of Blood, unlocked by an Undying Hate Timeless Jewel with Tribute to Tecrod. Sacrifice of Blood regens the entire life cost of skills over 8 seconds, and is further enhanced by other nodes in the passive tree, including Sanguimantic Rituals. Zealot’s Oath is allocated to apply the excess life recovery to Energy Shield, so Energy Shield Recharge effects are not necessary.

Damage

Rathpith Globe is the first key unique item to obtain to scale damage from Maximum Life. With this item providing Critical Hit Chance, along with Sunder the Flesh, Blindside, and nodes in the Passive Tree, 100% Critical Hit Chance with Lightning Warp can be obtained. Stack as much Critical Hit Chance as possible, up to 75% in the detail sheet of Lightning Warp for the Blind tech to reach the cap (Critical Hit Chance against Blinded Enemies is not reflected in the tooltip). A high Critical Hit Chance ensures consistent activation of Cast on Critical.

Atalui’s Bloodletting provides another massive damage boost of about 300% Extra Physical Damage, which is then converted to Cold Damage by Embitter to synergize with Elemental Weakness and Elemental Exposure.

Cast Speed is a priority stat for smooth gameplay and to increase damage output. Stack Cast Speed on your Wand, Amulet, Rings, Glove sockets, and nodes in the Passive Tree to spam Lightning Warp faster.

A high Cast Speed also benefits Spellslinger, which generates Energy based on the base Cast Time of the Spells you cast. Spellslinger is unlocked by equipping a Duelist Wand, and Ball Lightning is socketed for another trigger that can be cast on demand. The Spellslinger Ball Lightning is supported by Vilenta’s Propulsion, which grants Projectile Speed from the high amount of Cast Speed stacked in the build. This is the fastest traveling Ball Lightning to use for speeding through maps.

Infinite Lightning Warps

A gameplay loop is created for infinite Lighting Warps. Lightning Warp requires an enemy in culling range or Ball Lightning projectiles to cause an explosion. A manually cast Ball Lightning is required to initiate Lightning Warp, and then additional Ball Lightning projectiles and Arc are automatically triggered by Cast on Critical.

Arc applies Shock with 50% more magnitude, and it is empowered by Lightning Infusions created by Lightning Warp to deal 3 times more damage and chain additional times. The chaining Arcs hit enemies at a further distance, often placing them within culling range, allowing you to warp to them and apply Shock with 50% more magnitude.

Triggered Skills cannot generate Energy for more triggers. However, a Lightning Warp explosion still generates Energy even when exploding a triggered Ball Lightning Projectile or an enemy put into culling range by a triggered Arc.

Once Cast on Critical starts triggering Ball Lightning projectiles, Lightning Warp can be spammed indefinitely as long as enemies remain to be hit. Spellslinger also gains Energy to cast faster Ball Lightning projectiles on demand when needed.

Skill Rotation

Follow the basic skill rotation below to clear groups of enemies in maps:

1. Cast Ball Lightning supported by Multishot II and Unleash to fire multiple projectiles.
2. Cast Lightning Warp on Ball Lightning to teleport to them and cause an explosion. Damage dealt by Lightning Warp explosions generates Energy to trigger Arc and additional Ball Lightning projectiles from Cast on Critical. Continue to hold down the Lightning Warp button to jump on Ball Lightning projectiles and enemies in culling range.

Execute the steps below to optimize damage against bosses:

1. Cast Sigil of Power from a Chiming Staff equipped in Weapon Set 2 to buff damage.
2. Switch back to Weapon Set 1 (can be set to automatically swap) before casting Elemental Weakness to reduce the Resistance of the boss. Elemental Weakness can be pre-cast before a boss spawns if supported by Cursed Ground.
3. Cast Frost Bomb to apply Elemental Exposure.
4. Cast Ball Lightning supported by Multishot II and Unleash to fire multiple projectiles.
5. Cast Lightning Warp on Ball Lightning to teleport to them and cause an explosion. Damage dealt by Lightning Warp explosions generates Energy to trigger Arc and additional Ball Lightning projectiles from Cast on Critical. Continue to hold down the Lightning Warp button to jump on an unlimited supply of Ball Lightning projectiles.

Skill Gems, Spirit Gems, and Support Gems

The Infinite Lightning Warp Blood Mage utilizes the following Skill Gems, Spirit Gems, and Support Gems. Gem Sockets are listed in order of priority.

The Spirit Gem setup requires 137 total Spirit to activate Cast on Critical and Blink. Ensure you apply 20% quality to the Cast on Critical skill gem and allocate Efficient Inscriptions in the passive tree to reduce the Spirit reservation. Defeat The King in the Mists (Act 1), Ignagduk (Act 3), and Lythara (Interlude) to gain 100 base Spirit. Obtain the remaining 37 Spirit from your Amulet.

Equip a Chiming Staff in Weapon Set 2 to unlock Sigil of Power, which provides a damage buff against bosses. Ensure you set all your other skills to only be used with Weapon Set 1, so you automatically swap back.

Prioritize obtaining Atalui’s Bloodletting and Embitter to combo together for a massive damage increase. If you do not yet have both of these gems, replace them with Considered Casting and Magnified Area I.

The Skill Gems for Ball Lightning can remain as low as Level 11 to reduce its Life costs, since it is not relied upon to deal damage. All the other Skill Gems should be leveled as high as possible.

Perfect Jeweller’s Orb priority on Skill Gems: Lightning Warp > Cast on Critical > Ball Lightning > Frost Bomb.

Piety’s Mercy can replace Sione’s Temper in the Cast on Critical setup for the fastest version of the build. Less Ball Lightning are generated, but enemies hit by Arc will not be killed and remain in culling range for to cast Lightning Warp on them. Watch the Piety’s Mercy update video for gameplay footage utilizing this tech.

Ascendancy

Blood Mage is the recommended Ascendancy for the Lighting Warp Witch. The chosen Ascendancy can be switched within the base class by repeating your highest trial completion.

Allocate the Ascendancy nodes for Blood Mage in the following order:

1. Sanguimancy and Vitality Siphon — These nodes need to be allocated together to be able to sustain the Life costs of Skills with Spell Leech.
2. Sunder the Flesh — Sets the base Critical Hit Chance of Spells to 15%.
3. Grasping Wounds — The delayed damage taken drastically improves survivability against getting one-shot by allowing you time to recover Life.
4. Crimson Power — Energy Shield granted by your Body Armor also provides Maximum Life, which can amount to 1000+. The Maximum Life also scales damage output when Rathpith Globe is equipped.

Passive Skill Tree

In the Passive Skill Tree, utilize attribute nodes to fulfill any Intelligence and Dexterity requirements, and then allocate the remaining points to Strength for Maximum Life.

The following Passive Tree is the starter setup that prioritizes Critical Hit Chance, Critical Damage Bonus, Spell Damage, and Energy Shield nodes. Energy Shield recharge rate and start delay nodes are necessary for survivability when spending Life to cast spells. The starter setup assumes you do not yet have any key unique items.

The Passive Tree below is the final setup after you obtain an Undying Hate Timeless Jewel with Tribute to Tecrod (souls number value does not matter). Insert the jewel into the socket next to Chaos Inoculation to convert the keystone to Sacrifice of Blood. The Life spent on casting skills is regenerated over 8 seconds, and Zealot’s Oath allows the life regeneration to recover Energy Shield. This setup has the most survivability, without needing any Energy Shield Recharge nodes.

The final setup is optimized with the assumption that you equip Rathpith Globe for a massive amount of Critical Hit Chance and Increased Spell Damage, which diminishes the value of nodes with those stats.

The Atalui’s Bloodletting and Embitter interaction enables the Freeze nodes in the Passive Tree.

Unique Items

The following recommended Unique Items for the Lightning Warp Comet Blood Mage are listed below:
