Rare Alchemical Bomb Consumable Mental Splash Source Season of Ghosts (Hardcover) pg. 295Usage held in 1 hand;
Bulk L
Activate [one-action] Strike
This rare alchemical bomb gathers and concentrates the emotions that linger in a burial ground where generations of beloved ancestors have been interred, infusing that powerful emotional energy into the alchemically prepared powdered
silver stored within the bomb. This energy glows with a soft, silver radiance and, if stored in a clear container, allows a silversoul bomb to be used as a
torch to illuminate an area.
A silversoul bomb grants an item bonus to attack rolls and deals mental damage plus additional effects, according to the bomb’s type.
Nindorus are particularly harmed by silversoul bombs and take the listed persistent mental damage, according to the bomb’s type. Against nindorus, the bomb’s item bonus also applies to its save DC to resist being
dazzled or
blinded. Creatures that have
weakness to silver (including most nindorus) have an equal amount of weakness to the mental damage caused by a silversoul bomb, due to the silver infused into the energy within.
