Unspecified Number of Magical Tattoo Uses and Flavoring Ideas

[Third Mind]

Ok, so I love the idea of Magical Tattoos and how'd they look and be used in pathfinder. That being said I feel that I alone cannot fully tap the well of ideas for flavor and uses of the tattoos. So, I come to the fine message boards of Paizo itself to search for more ideas and inspirations. Of course I intend to contribute and will do so starting here.

1) - Black tribal wings adorn the shoulder blades, one each. With but a command and a feint blue aura, real full wings grow from their tattooed origins allowing the user to fly (for an unspecified amount of time).

2) - A tattoo of a heart with a keyhole lies upon the chest. The user may absorb up to 3 levels of spells using the magical tattoo. When used, the keyhole glows as if the magical energy was stored just behind it.

3) - An inked serpent coils around the forearm, eyes red and somehow angry. When the command word is spoken, the snake animates uncoiling itself from the forearm and materializing in front of it's owner. For X duration the user may command the snake as they wish. They may also see through the eyes of the snake as a standard action, but become unaware of their immediate surrounding visually if they do so.

----------------------

A bit wordy perhaps, but I'm hoping to see some good ones if people are willing to contribute their ideas.

The Ouroboros - Two entwined serpents eating each other. When the command word ist spoken, the searpents writhe and trash, swallowing eatch other even more savagely until they engulf their owner, who vanishes into nothing.
Lesser version: A simple Vanish spell, followed by a temp. hp buff on becoming visible again.
Greater version: The Tattoo casts Maze on the owner. After reentry into the real word, the owner gains a number of temp. hp egal to 10 per round he was away.

Nice. I like that.

Here's a couple more:

Lockbox = The likeness of a lockbox with a slit just big enough for a common gold coin, chains dangling from two of it's sides.

When a coin is pressed to the slit of the lockbox it is stored inside of the tattoo (treated as a sort of extra-dimensional space) up to a maximum of 1,000gp. When the user desires, they may retrieve as many coins as they wish stored in their tattoo by holding their hand to the tattoo and giving a thought.

Shatter Shield = On the back of each hand is one half of a whole shield, seemingly broken in two. When the user brings their fists together, end to end, the shield looks whole once more and they gain the benefit of the magical tattoo.

While holding their hands in such a way they gain a +4 shield bonus to their AC. However, due to having to hold their hands in such a way, they cannot cast any spells with a somatic component. When the tattoo owner drops their hands for whatever reason, they immediately lose the bonus to AC.

I'm not all that great at explaining the rulings part. But hopefully it is clear enough.
