Elemental Ground Surfaces | PoE2 Mechanic

What Elemental Ground Surfaces does

Current rules

Check the creating skill or item first. It determines whether the surface is allied or hostile, how long it lasts, and whether it replaces a default value. A detrimental surface normally does not affect its creator or allies, but skills that explicitly interact with Elemental Ground Surfaces can still use eligible allied or enemy surfaces.

Three elemental surfaces: Ignited Ground repeatedly applies Flammability and begins Igniting at 50% total Flammability. Chilled Ground applies Chill. Shocked Ground applies Shock.
Ownership controls ordinary effects: A detrimental ground effect does not normally affect its creator or the creator's allies. A beneficial ground effect does not normally affect enemies unless it also has a detrimental component.
Explicit skill interactions can use surfaces: Some player and minion skills explicitly absorb, pass over, or count Elemental Ground Surfaces. The skill wording determines whether an enemy surface is eligible and what bonus it grants.
Creating and counting are different: Berek's Pass, Berek's Respite, and Berek's Grip do not create ground. They make eligible Wind Skills count as being boosted by Chilled, Ignited, or Shocked Ground respectively.
Multiple surface boosts require explicit permission: The Taming makes eligible Wind Skills count as boosted by all three elemental surfaces and lets those skills receive multiple Elemental Ground Surface boosts. Without such wording, do not assume the three bonuses stack.

Ground duration and area supports

Persistent Ground supports extend surface duration. Encroaching Ground makes supported surfaces grow over time. Higher Persistent Ground tiers can prevent early destruction and add Suppressive Ground.

Limits and exceptions

3 rules

An Elemental Ground Surface is not automatically a damaging area. Its named effect and creating source determine what it applies.
The ground's duration, radius, ailment value, and damage basis can be replaced by the wording on the creating skill or item.
A ring that makes a Wind Skill count as boosted by a surface does not create that surface on the map.

skillTwister

Whip up a twister with a flick of your Spear. The twister moves forward erratically, Blinding and repeatedly Hitting enemies within. If a twister touches a Whirlwind from your other skills, it Consumes the Whirlwind to create additional twisters that deal more damage. Passing over Elemental Ground Surfaces or Consuming an elemental Whirlwind will grant twisters extra damage of that element.

skillTornado

Create a storm that sucks in enemies and deals Physical damage over time. A Tornado that overlaps an Elemental Ground Surface absorbs that surface's Debuff, applying it to enemies inside the Tornado and causing the Tornado to deal extra damage of that element.

skillEye of Winter

Fire a single Eye Projectile which does not Hit enemies. The Eye constantly releases damaging shard Projectiles in a spiral as it flies. If the Eye passes over an Elemental Ground Surface or Orb, it will take on that surface's effect causing shards to deal more damage of the corresponding Type.
