Wondrous Item, uncommon
A magical spray bottle. Iridescent multi-colored liquid sloshes inside of it, giving off a slight glow.
Spraying this liqud on any surface causes it to stick to it, unable to removed by non-magical means and visible to you and any creatures of your knowledge of your choice through any non-magic barriers or surfaces. To change the color of the liquid you spray, you must imagine that color in your mind. The spray cannot be multi-colored. When this item's charge is fully depleted, you can expend one level one or higher spell slot to refill it with liquid instantly.
