Lich Thor Mjolner Endgame Build

Due to the latest balancing changes, we do not recommend playing this build anymore, as it does not meet the high standards we apply to our guides in terms of fun and performance. We are leaving it up as a reference and it might be revived in a later patch.

Introduction

This guide requires a rework due to The Deepest Tower being removed from the game in The Third Edict League. We will do our best to get the guide updated as soon as possible. Please check back at a later time during the league.

The Thor Lich Witch dual-wields Mjolners to trigger Lightning Spells on Melee hit. This hybrid build utilizes both Melee Attacks and Spells, but the majority of damage output is dealt by Lightning Warp. The devastating damage of Lightning Warp is capable of instantly deleting max difficulty pinnacle bosses. Trampletoe is equipped to spread Lightning Warp damage to additional enemies for more effective map clearing.

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.

Strengths and Weaknesses

Build Mechanics

Dual-wielded Mjolners unlock two Thundergod’s Wrath Skills, which gain Energy when you hit enemies with Melee Attacks and trigger socketed Lightning Spells on reaching Maximum Energy. Ball Lightning is triggered from the first Thundergod’s Wrath, and then Lightning Warp is triggered from the second Thundergod’s Wrath to deal the majority of damage output in this build.

Leap Slam and Mace Strike are the Melee Attacks used to generate Energy for Thundergod’s Wrath. The amount of Energy generated by Melee Attacks is modified by the percentage of the enemy’s Ailment Threshold the hit will deal, so increasing Leap Slam and Mace Strike damage results in more triggers to deal damage. Therefore, the Thor Lich focuses on damage scalars that apply to both Melee Attacks and Spells utilized in the build.

Damage Scaling

To scale the hybrid damage utilized in this build, a massive amount of 420% Increased Damage with Hits against Enemies that are on Low Life is allocated in the Passive Skill Tree. Damage is also Lucky against enemies that are on Low Life, which is especially beneficial for Lightning damage due to its wider damage range. Enemies usually have to be at 35% of their Maximum Life or less to count as being on Low Life, but the Deepest Tower is equipped to apply the Low Life bonuses at all times.

Another valuable scalar for all the Skills is Extra Chaos Damage, which is obtained from weapon runes and Unholy Might in the Lich’s ascendancy. Original Sin is equipped to convert all Elemental Damage to Chaos Damage for better synergies with Extra Chaos Damage, Withering Touch, and Despair.

Speed-Farming Maps with Trampletoe

Trampletoe is equipped for additional explosions when dealing Overkill Damage to enemies. The Increased Damage Against Low Life Enemies and Extra Chaos Damage obtained in the build also scale these explosions from Trampletoe. An interesting feature causes these scalars to be applied each time an enemy is killed, triggering a chain reaction that results in screen-wide clearing.

Defensive Layers

Proper defenses are necessary for the Thor Lich to survive while leaping into packs of enemies. Multiple layers of defense drastically improve survivability to make this build feel tanky.

Life and Energy Shield are combined for a high effective hit pool. A body armor is equipped to grant base Evasion Rating and Energy Shield, and then both stats are scaled by hybrid nodes in the Passive Skill Tree.

Defensive persistence buffs are also utilized, since the build already has more than enough damage output. The Temporal Chains aura activated by Blasphemy slows enemies down to make it difficult for them to land hits. Wind Dancer provides more Evasion Rating and knocks enemies back when they hit you.

Skill Rotation

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

1. (Optional) Swap to Weapon Set 2 to cast Blink up to two times to traverse quickly.
2. Cast Leap Slam to land on top of enemies from a distance. The landing animation can be canceled by using Dodge Roll to cover more ground.

Execute the steps below to optimize damage against bosses:

1. Cast Despair to lower Chaos Resistance. This debuff can be pre-cast before a boss spawns if supported by Cursed Ground.
2. Activate Mana Tempest to apply Extra Lightning Damage to Lightning Warp.
3. Repeatedly swing with Mace Strike, rapidly triggering Ball Lightning and Lightning Warp to deal damage.

Spirit Gems

The Spirit Gem setup requires 124 total Spirit to activate Blasphemy, Overwhelming Presence, Wind Dancer, and Precision. Ensure you apply 20% quality to the Blasphemy Skill Gem for 10% Reduced Reservation. Defeat The King in the Mists (Act 1, Normal Difficulty) and Ignagduk (Act 3, Normal and Cruel Difficulty) for 100 base Spirit. Obtain the remaining 24 Spirit from a corrupted Deepest Tower or an Amulet.

An optional Blink Swap Tech can be utilized to traverse maps quickly. Set Overwhelming Presence and Wind Dancer to only be used with Weapon Set 1, and then select Blink to only be used with Weapon Set 2. Use the Weapon Swap button to cast Blink in Weapon Set 2. Make sure you switch back to Weapon Set 1 to deal damage.

Skill Gems	Support Gem 1	Support Gem 2	Support Gem 3	Support Gem 4	Support Gem 5

Ascendancy

Lich is the recommended Ascendancy for the Thor Witch build due to its damage increases and Mana sustain. The chosen Ascendancy can be switched within the base class by repeating your highest trial completion.

Allocate the Ascendancy nodes for the Lich in the following order:

1. Necromantic Conduit and Soulless Form — These nodes need to be allocated together to recover the 5% of Maximum Mana lost per second with the Mana regenerated equal to 6% of Maximum Life per second. Soulless Form makes it easy to sustain Leap Slams without needing any other sources of increased Mana Regeneration Rate, as long as you have enough Maximum Life. Necromantic Conduit grants 30% extra Chaos damage that synergizes well in this Chaos-focused build.
2. Eldritch Empowerment — 30% more damage applies to Lightning Warps. Triggered Skills ignore the downside of additional Energy Shield cost due to Thundergod’s Wrath removing all costs.
3. Crystalline Phylactery — Unlock an extra jewel socket that doubles stats. Socket your best Rare Jewel into this socket for best results.

Passive Skill Tree

In the Passive Skill Tree, use attribute nodes to fulfill any Intelligence and Dexterity requirements, and then allocate the rest as Strength for Maximum Life.

The following setup is the default version of the build, optimized for a balance of damage, survivability, and speed. Weapon Set Skill Points are allocated to switch nodes from damage to Cooldown Recovery Rate for the Blink Swap Tech.

The Skill Tree tool is missing three nodes allocated with Skill Points from Weapon Set 1. Socket a From Nothing Diamond granting allocation of passives in the radius of Unwavering Stance into any Jewel socket. Then allocate Finality and two Damage against Enemies on Low Life nodes. If you are using the Blink Swap Tech, these damage nodes are allocated in Weapon Set 1 and switched to Cooldown Recovery Rate nodes in Weapon Set 2.

Unique Items

The following Unique Items are required for the Thor Lich:

• Mjolners are dual-wielded in both weapon slots to unlock two Thundergod’s Wrath Skills. These Skills trigger Ball Lightning and Lightning Warp on melee hit to deal the majority of damage output in this build.

• Trampletoe spreads Lightning Warp damage to a further range to kill more enemies. The massive damage dealt by Lightning Warp causes high Overkill Damage to explode killed enemies. Trampletoe explosions benefit repeatedly from increased Damage and Extra Chaos Damage stats to cause a chain reaction.
• Original Sin converts all Elemental Damage into Chaos Damage for better synergies with Withering Touch, Despair, and Extra Chaos Damage.

Jewels

Socket Jewels into the multiple Jewel sockets unlocked in the Passive Skill Tree to significantly improve the performance of the build.
