Best Synergies with Earthshatter and POE2 Currency Exploding Earth Spikes in Path of Exile 2
Path of Exile 2 introduces a range of new and reworked skills, and among the most powerful for melee builds is Earthshatter. This slam-based attack creates Exploding Earth Spikes, making it a devastating choice for area damage builds. However, to maximize its potential, you need to pair it with the right support gems, passive skills, ascendancies, and gear.

This guide breaks down the best synergies for Earthshatter, helping you create an optimal high-damage melee build that can clear packs of enemies with ease and dominate bosses.

How Earthshatter Works
Earthshatter is a slam attack that creates spikes of earth radiating from the impact point. These spikes remain dormant until detonated, either by war cries or after a short duration. When triggered, they explode, dealing massive area-of-effect (AoE) damage.

Since Earthshatter's primary strength lies in these explosions, its best synergies involve:
Triggering the explosions quickly for faster damage output.
Maximizing melee slam damage increases the power of each initial hit.
Scaling physical damage and AoE for bigger explosions and more coverage.

Let's explore the best synergies to enhance Earthshatter’s effectiveness.

1. Best Support Gems for Earthshatter
To maximize Earthshatter’s damage, attack speed, and explosions, use these support gems:

Pulverise Support – Increases slam damage and AoE, making Earthshatter’s spikes cover a larger area.
Fist of War Support Periodically empowers Earthshatter, greatly Ruthless Support – every third attack deals massively increased damage, ideal for Earthshatter’s slow but heavy-hitting nature.
Increased AoE Support – Expands the radius of Earthshatter’s spikes, improving clear speed.
Brutality Support removes all elemental scaling but greatly enhances physical damage.

If you want to focus on boss damage, replace Pulverise with Conc Effect (Concentrated Effect) for a stronger single-target slam.

2. Warcries for Exploding Earth Spikes
To trigger Exploding Earth Spikes, you need Warcries. These abilities instantly detonate all Earthshatter spikes, maximizing burst damage.

Seismic Cry – Increases slam damage and sends out shockwaves that detonate spikes across a larger radius.
Enduring Cry provides life regeneration and endurance charges, keeping you tanky while detonating spikes.
Intimidating Cry boosts damage against enemies by making hits double their damage calculation.

Use these war cries strategically to ensure continuous detonations of Exploding Earth Spikes.

3. Best Passive Tree Investments
To maximize Earthshatter’s damage and AoE, invest in the following passive skill tree clusters:

Primary Focus:
Slam Damage Nodes – Found near the Marauder starting area.
Physical Damage Nodes – Increases both the slam hit and explosion damage.
Warcry Cooldown Reduction – Shortens warcry cooldowns so you can detonate spikes more frequently.
Attack Speed Nodes – This helps with smoother animation cancels and faster warcry use.

Optional Nodes for Defense:
Endurance Charge Generation helps sustain physical mitigation and survivability.
Armor & Life Leech Nodes – For tanky playstyles. Stun Avoidance Prevents interruptions during attacks.

These passives ensure that Earthshatter’s spikes explode quickly and buy Path of Exile 2 Currency with maximum force.
