Since Ground Slam is a pure physical damage skill, increasing your weapon damage is the best way to POE2 Currency boost its output. Two-handed weapons, particularly maces and axes, tend to have high base physical damage, making them ideal for Ground Slam builds.

Key Passive Nodes:

Melee Physical Damage (Increases raw damage output)
Two-Handed Weapon Damage (Improves effectiveness with maces and axes)
Strength Scaling (Boosts both damage and survivability)
2. Increased Area of Effect (AoE)
Expanding Ground Slam’s cone-shaped area allows you to hit more enemies, making it more effective for clearing mobs.

Best Support Gems for AoE:

Increased Area of Effect Support (Wider shockwave range)
Pulverize Support (Expands AoE and increases damage)

While Ground Slam isn’t necessarily a fast-attack skill, increasing attack speed allows for more frequent slams, meaning more consistent AoE damage.

Best Attack Speed Boosters:

Faster Attacks Support
Multistrike Support (repeats slams, increasing total damage output)
4. Stun and Crowd Control

Best Stun Enhancers:

Endurance Charge on Stun Support (generates endurance charges for more survivability)
Mace Mastery (increases stun duration and effectiveness)
Best Weapon Types for Ground Slam
While Ground Slam can technically be used with different weapons, it works best with two-handed maces and axes due to their high base physical damage and stun potential.

Recommended Weapon Choices:
Two-Handed Maces: Best for stunning enemies and dealing high raw damage.
Two-Handed Axes: They offer better attack speed while maintaining high physical damage.
For those who prefer one-handed weapons, Ground Slam can still be viable, but it will lack the sheer power that comes with two-handers.
