Greater Thunderclap
- 3rd Level Evocation Spell
- Secret Crafts: Airologist
- Casting time: 1 action
- Range: self
- Components: S
- Duration: Instantaneous
- You clap your hands, emitting a peal of thunder. All creatures within 20 feet of you take 8d4 thunder damage and are deafened for 1d8 rounds, or take half damage and aren’t deafened with a successful Constitution saving throw. A creature that fails the saving throw by 5 or more is also stunned for 1 round. This spell doesn’t function in an area under the effect of a silence spell. Very brittle material such as crystal may be shattered if it’s within range, at the GM’s discretion; the GM can allow a character holding such an object to protect it with a successful Dexterity saving throw.
