Hide

With the Hide Action, you try to conceal yourself. To do so, you must make a DC 15 Dexterity Check (Stealth) while you’re Heavily Obscured or behind Three-Quarters Cover or Total Cover, and you must be out of any visible enemy’s line of sight; if you can see a creature, you can discern whether it can see you. 
On a successful check, you are Hidden. Make note of your check’s total, which becomes the DC for a creature to find you with a Wisdom Check (Perception).
