Effect If your next action is to cast an acid or poison spell that deals persistent damage, any creature who takes persistent damage from the spell is also Sickened 2 until the persistent damage ends. Using an action to retch can reduce the sickened value as normal, but it can't reduce the sickened value below 1 until the persistent damage ends.
Traits
Effects with this trait deal acid damage. Creatures with this trait have a magical connection to acid.
Spellbooks are useful tools for any magic user to write down incantations and runes of power, but where most spellbooks are nothing more than ink on parchment, grimoires have absorbed the magic of the spells within—magic that knowledgeable spellcasters can use to augment their spells.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
