Gain proficiency in the Stealth skill, if you already have proficiency, double your proficiency bonus. Additionally, you can spend 1 minute creating camouflage for yourself. You must have access to fresh mud, dirt, plants, soot, or other naturally occurring materials with which to create your camouflage.
Once you are camouflaged in this way, you can try to hide by pressing yourself up against a solid surface, such as a tree or wall, that is at least as tall and wide as you are. You gain a +10 bonus to Dexterity (Stealth) checks as long as you remain there without moving or taking actions. Once you move more than 5ft per action or take an action or a reaction, you must camouflage yourself again to gain this benefit.
