Doom Mechanic Hexes Curse

PoE 3.20 Changes: The Doom mechanic has been removed, to simplify the Hex system. Anything related to Doom has been reworked so that it's comparable to before. PoE Curses Changes Balance Manifesto 3.20.

The Doom Mechanic
Another issue that we feel undermines Hex builds is the Doom mechanic. We designed Doom with the goal of making self-cast Hexes more effective than other more trivial applications of Hexes, such as the Blasphemy and Hextouch Support gems. The Doom mechanic was somewhat successful in its goal, but came at the cost of adding a lot of complexity to Hex-related mechanics.

We are removing the Doom mechanic and as a consequence will be making several other changes to mechanics that previously interacted with Doom. For example, all stats that reference Doom have been replaced with other curse-themed stats.

Hexblast has had its skill mechanics and damage adjusted to account for the loss of Doom's scaling. Impending Doom has also had its base damage roughly doubled to compensate for this loss. We have replaced the Doomsday keystone with a new Hex-themed keystone.

If the Hex was self-cast, the curse will gain Doom over time. Doom increases the effectiveness of the curse (1% per Doom). Maximum Doom is capped at 30 by default. Each Hex has its own Doom counter. Triggered curses are not counted as self-casted.

What is Doom Mechanic

The new Doom mechanic causes a self-cast Curse to increase in intensity over time until it expires. This works well in conjunction with the Impending Doom Support Impending Doom Support, which causes an explosion of chaos damage when a linked curse ends.

What is Doom Mechanic

Changes to Curses

Many curses are now classified as Hexes and now use the ‘Doom’ mechanic. Self-cast Hexes build up to Doom the longer they’re active, increasing their effect.

use the Doom mechanic

If I cast a curse (e.g. Flammability) and it's gaining Doom, and I re-cast it on the same target, does the Doom counter reset? Or is the curse duration refreshed but the existing Doom counter remains, and will continue to count up if possible?

The new Hex replaces the old one, because they cannot both exist.. Each hex has its own doom.
