Texture Surprise

This spell is a minor magical trick which allows a caster to alter the appearance of an inanimate object. The object must be a smooth flat surface no larger than one square foot. The spell is able to apply the following effects in any combination when cast. 

• Change the color of an object.
• Change the texture of an object.
• Make a color, a small mark, or a symbol appear on an object or a surface.

Spells such as true sight, detect magic and identify will reveal the deception. The spell can be cast multiple times to affect a larger surface but doing so makes the deception easier to detect.  After three casts to achieve a single effect an investigation check versus the spell DC will reveal the deception. Each cast beyond three to achieve a single effect provides a +1 to investigation checks to detect the deception. At levels 5, 11, and 17 the DC of such checks increases by 1.

Dispell magic will end the effect. The caster may use an action to end the effect as well.

The caster can make an alteration permanent by imparting a piece of his essence into the material. By doing so the caster takes 1d4  necrotic damage and their maximum hit points are reduced by that amount. This is true for each item the caster makes permanent and each item the caster make permanent can be no larger than a one square foot surface. The caster cannot use this ability to make an effect permanent if it were to reduce his hit points below one.  The reduction of the caster's maximum hit points cannot be restored until the effect is dispelled and the caster takes a long rest.
