Skill functions and interactions

Accuracy: Sunder only needs to pass an evasion check to cause a shockwave on a specific enemy – the shockwave will hit all enemies in its range, regardless of evasion.
Area of Effect: Increases to area of effect will increase both the area of the wave and that of the shockwave created. Note however that only the wave's width is modified. The length of the wave is either constant or the impact of aoe is much smaller.

Item acquisition

Sunder can drop anywhere. Drop level: 12.

Sunder 3.11 Changes

Now slams the ground, creating a slow wave of churning terrain that damages enemies in a sequence of areas in front of you. Enemies hit by the wave will release a damaging shockwave in an area around them. Using the skill again will stop the previous wave. Requires a Mace, Sceptre, Axe, Staff or Unarmed.
The wave creates 5 areas, and cannot stop before creating 2 areas.
There is a delay between areas the wave creates. The gem gains reduced delay between areas as it levels, up to 25% reduced delay between areas at gem level 20.
The wave can cause a shockwave from up to 5 enemies.
The wave gains +2 to the radius of each area in the sequence.
Shockwaves now deal 40% less Damage (from 60%).
Now gains more area of effect as the gem levels, up to 19% at gem level 20.

Sunder 3.11 Build Guide

As part of GGG’s effort to encourage slower and heavier-hitting Slams, Sunder has become a much wider and longer but slower cascade. Using Sunder while one cascade is still in motion will cause the existing cascade to end prematurely. These cascades will always travel a minimum length, so you can still use Sunder effectively with Multistrike and fast hitting weapons when close to enemies.

It still releases Shockwaves which can overlap when they hit enemies. Leveling the gem no longer scales its radius but instead scales its Area of Effect. Overall it now provides a better Area of Effect for slower hitting weapons.
