Effect You use a piece of chalk to write up to 25 words on a slate. As you write, the writing also appears on the other slate in its matched pair, no matter how far away it is, as long as it is on the same plane. Wiping one slate clean erases the writing from both slates. Each slate can be activated once per hour.
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.
DivinationThe divination school of magic typically involves obtaining or transferring information, or predicting events.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school 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.
