Cursed Ground Support Gem

Related: Doomsday keystone

Doomsday is a keystone passive skill that modifies Hex spells. When casting the Hex spell, instead of applying the curse which gains Doom over time, the spell creates a Hexed Area for 1 second. Enemies in the Hexed Area receive the curse, and after 1 second, the Hexed Area expires and applies the maximum amount of Doom to enemies standing in it.

Your Hex Curse Spells create a Hexed Area for 1 second if you Cast them yourself
Enemies in the Hexed Area are Hexed, and the Hex does not expire while in the Hexed Area
Hexes applied this way do not gain Doom over time
Hexes in the Hexed Area gain up to maximum Doom when the Hexed Area ends

Hexes

Hexes are spells which apply the curse in an area of effect.

Hexes have reduced effectiveness against bosses and certain unique enemies. Act and map bosses, Conquerors of the Atlas , Incursion architects, Immortal Syndicate members, Breachlords have 33% less Hex Curse Effect. Sirus, the Shaper, the Elder, Shaper and Elder Guardians, The Black Star, The Searing Exarch, The Infinite Hunger, The Eater of Worlds, and The Maven have 66% less Hex Curse Effect.

Hexes can be turned into an aura by linking it with either Blasphemy Support or Awakened Blasphemy Support.

Hexes can appear as modifiers on equipment and maps, which applies the Level 1 version of the curse on the specified target. Increased curse effect listed on the modifier is relative to the Level 1 version of the curse.

Hexes that are re-applied will replace the older Hex and reset Doom, but will not cause Doom Blast to trigger.
