During combat a player of mine wanted to climb an easily scaled 10' rock wall. Normally climbing requires extra Movement costs, and I called for a DC 10 Strength (Athletics) check to make the climb without a rope. His intention was to climb atop a cliff and then use his Attack Action. My question is would climbing consume his Action?
I'm aware of the Use Object Action when using an object that would consume your action and not fall under the 'free object interaction' category, but does 'interacting' with a wall (i.e. climbing) count as an Action normally or is it simply part of your Movement?
