This tattoo consists of numerous asterisks at regular intervals along the fingers of one hand, perfect for measuring stars against the horizon. When used against a clear night sky, the tattoo grants a +2 circumstance bonus to Survival checks to Sense Direction and counts as a compass for the purpose of that action.

Effect The dots of the tattoo turn to points of light and fly above the head of a creature within 30 feet, where they form a three-star constellation that guides your spells further than they could normally travel. The constellation sheds dim light and remains visible even if the creature hides, aiding in locating it. Furthermore, while the constellation lasts, if you Cast a Spell that has a range and that spell would affect only the marked creature, the spell's range is increased by 30 feet. As is standard for increasing spell ranges, if the spell normally has a range of touch, you extend its range to 30 feet. Each time you use this benefit, one of the stars above the creature's head winks out; when all three have winked out or after 1 minute has passed, the effect ends.
Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
DivinationThe divination school of magic typically involves obtaining or transferring information, or predicting events.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
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.
TattooA tattoo is a type of item that is drawn or cut into a creature's skin and usually takes the form of images or symbols.
