Area 60-foot line
Saving Throw Fortitude
You unleash a wave of death to snuff out the life force of those in its path. Each living creature of 17th level or lower in the line must attempt a Fortitude save. If the damage from massacre reduces a creature to 0 Hit Points, that creature dies instantly. If massacre doesn't kill even a single creature, the void energy hungrily turns backward toward you, dealing an additional 30 void damage to every living creature in the line (even those above 17th level) and 30 void damage to you.
Critical Success The creature is unaffected.
Success The creature takes 9d6 void damage.
Failure The creature takes (ternary(gte(@item.rank,10),115,100)) void damage.
Critical Failure The creature dies.
Heightened (10th) The spell can affect living creatures up to 19th level. Increase the damage to 10d6 on a success, and to 115 on a failure.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ConcentrateAn action with this trait requires a degree of mental concentration and discipline.
DeathAn effect with the death trait kills you immediately if it reduces you to 0 HP. Some death effects can bring you closer to death or slay you outright without reducing you to 0 HP.
ManipulateYou must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
VoidEffects with this trait heal undead creatures with void energy, deal void damage to living creatures, or manipulate void energy.
