--- The shatter spell releases an eardrum-rupturing sound, cracking the crystal wall. Not to be confused with the previous entry, thunder refers to damage caused by an intense shockwave of sound. In fact, it was known as ‘sonic damage’ in 4th edition. It’s one of the stronger damage types in DnD, having only a few resistant or immune monsters, and being strong against earth elementals. It’s also quite rare that you’ll come up against it. If you want to avoid thunder damage, be careful not to piss off any Djinn.
