When playing in Discord, you must also follow Discord’s Terms of Service and Community Guidelines.
3. Health and safety
Some games use rapidly changing colors, sounds and vibration. If you have a history of photosensitive epilepsy or are sensitive to visual or audio stimuli, take care before playing and stop immediately if you feel unwell. Keep the volume at a safe level when using headphones.
