Sunder is a melee slam attack skill that creates a slow-moving area of effect wave forward. Enemies hit by the wave release circular shock waves that further damage nearby enemies. The wave continues to move past its minimum distance until a new wave is created. Requires an axe, mace, scepter, staff, or unarmed.

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.

2.2.0	Added to the game
