Activate 
envision
Effect Abraxas transforms the tattoo into a weapon of your vengeance. The vengeful arm crawls into your hand and becomes a Retribution Axe. You can use this activation again while holding the axe to revert the vengeful arm to a tattoo. Like other retribution axes, you can etch fundamental runes into the vengeful arm's retribution axe to increase its potency or to add striking.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
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.
