Skill Check Basics in D&D 5e

Skills are ability checks tied to specific abilities. Acrobatics uses Dexterity, Athletics uses Strength, and so on. When a character is proficient, they add their proficiency bonus. Expertise doubles the proficiency bonus for that skill. Passive skill scores equal 10 + modifiers and are used for detecting hidden threats or noticing clues without active rolling.

Advantage and disadvantage follow the normal rules: roll two d20s and use the higher or lower result. Characters can gain advantage from spells like Enhance Ability or features such as Familiar help actions. Disadvantage applies due to conditions like exhaustion or heavy armor on Stealth checks.

Examples and Tips

A Rogue with Dexterity +5, proficiency bonus +4, and expertise in Stealth would select Stealth, expertise, and roll to see if she beats a DC set by the DM. Passive Stealth can be turned on to compare against foes using passive perception. A DM can use this tool to roll contested checks between NPCs and PCs, or to quickly look up passive Insight when gauging deception.
