DOOM

Domain-Exclusive Homebrew Spell

Prerequisite: Active Domain
Range: The active Domain
Duration: Until the technique resolves or the caster is killed

When you activate DOOM, you create a massive spherical Domain centered on yourself. From the outside, the Domain appears completely black, absorbing surrounding light and resembling a black hole.

All hostile creatures within the Domain are trapped inside and cannot leave while DOOM is active.

While DOOM is charging, you become completely immobile. You cannot move, make attacks, or cast spells. A glowing blue oval-shaped barrier forms around you, protecting you from the creatures trapped within the Domain.

The barrier can be attacked and destroyed by creatures inside the Domain. If the barrier is destroyed, you immediately lose half of your current hit points. DOOM does not end when the barrier is destroyed. You remain completely immobile and unable to attack, move, or cast spells, leaving you exposed to the creatures within the Domain.

The creatures must then kill you before DOOM finishes. If you are killed while DOOM is charging, the technique immediately ends and the Domain disappears. All surviving creatures affected by DOOM regain 1d10 hit points.

If you survive until DOOM resolves, every hostile creature within the Domain is affected according to its current hit points.

A creature with 50 hit points or fewer has its hit points reduced to exactly 1. Immediately afterward, a massive sphere of energy forms around you and expands outward like a shockwave. The shockwave deals exactly 1 damage to everything it reaches. A creature reduced to 1 hit point by DOOM is therefore defeated when the shockwave reaches it.

A creature with more than 50 hit points has its current hit points reduced to one-tenth of their current value. The creature is then immediately ejected from the Domain and takes 1d8 damage upon being expelled.

The Domain itself appears as a gigantic black sphere that absorbs surrounding light. At its center, the caster remains completely motionless inside the glowing blue barrier. As DOOM reaches its final stage, an enormous sphere of energy originates from the caster and expands outward across the Domain as a devastating shockwave.

DOOM gives the caster overwhelming power, but leaves them completely vulnerable while the technique charges. Destroying the barrier is only the first step. The caster must be killed before the technique finishes to prevent DOOM from resolving.
