Bubble Tattoo

Alter: As an action, you can speak the tattoo’s command word to cause it to completely separate from your skin and surround you in an inky bubble for 1 minute or until you dismiss it as a bonus action. The bubble is weightless and just large enough to contain the creature or object inside. You are able to see and hear outside your bubble, but other creatures are unable to see and hear inside your bubble. The atmosphere inside your bubble is comfortable and dry, and you are able to roll your bubble around up to half your walking speed. The bubble can be picked up and moved by other creatures.
Nothing—not physical objects, energy, or other spell effects—can pass into, through, or out of the bubble, though a creature in the bubble can breathe there. The bubble is immune to all damage, and a creature or object inside can’t be damaged by attacks or effects originating from outside, nor can a creature inside the bubble damage anything outside it. A disintegrate spell targeting the bubble destroys it without harming anything inside it.
Once used, the tattoo can’t be used again for 1d4 days

Produced by a special needle, this magic tattoo symbolizes three perfect spheres.

Many protective magical properties granted by items are often short-lived, sometimes only lasting for a few seconds, or are out of reach for those that do not possess magical abilities to begin with. This tattoo was developed by an aspiring tattooist who sought to infuse longer-lasting protective magic directly onto one’s skin. He hoped that when activated, a person would find themselves in a tiny, mobile, spherical shield. Many a tale has since been told of people found guilty of some crime in their village manifesting a bubble and rolling away to evade punishment.
