Thunder
You create a burst of thunderous sound that can be heard up to 100 feet away. Each creature within range, other than you, must succeed on a Constitution saving throw or take 1d6 thunder damage.
The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).

Did you read the spell? It says range 5'. It can be heard 100' away but only causes damage to anyone within 5' of caster.
It can be heard 100 feet away, but the effect range is still only a 5ft radius centered on you. As Benz74M mentioned, it affects all creatures within 9 adjacent squares including your own, and you're immune to the damage.
The 100 ft statement is a perception flavor-text, like the sound the Knock spell makes. Note the Range/Area stat at the top. For a cantrip to have a 100 ft effective range on ALL creatures would be ridiculously broken, even if they take no damage on a successful save.
I read it the same, with one exception. The center of the sphere can be any square within 5ft of you. Otherwise it would have a range of (self), like Spirit Guardians, and describe the area in the text. I imagine this as reaching out and clapping or snapping magically hard in an adjacent space.
So pick any square within 5ft as the center, and anything within 5ft of that is affected. Basically the same thing you said, but with the option to shift the center by 5ft in any direction.
Two big reasons this matters: Allies can be closer (one row behind you) without taking damage. Distant spell can be used, because it’s not a Self spell (now you can move the center out to 10ft, meaning allies can still be one row back).
Two problems with that. 1 this isn't listed as a 5 ft sphere spell, it's just a 5 ft range. 2nd it doesn't tell you to designate an place to center the spell, it effects each creature in your range.
And to the people saying this is the same as a 15 foot sphere it's not. Dnd would define it as a 5 ft sphere, since it uses radius. 15 ft would be it's diameter, or 10 ft would be depending on how you translate diamater on a grid.
Wait how much damage does it do?
Thought one: Should not have a "can be heard from" for juat flavour, if it doesn't relate to targeting, it only makes confusion worse.
Thought two: Range needs clarified extremely badly.
What if as a Moon Druid, you are a Mammoth or some other Big creature, the Range of 5 ft from you, does that make it a larger Area of effect? or would the AoE be fully enclosed within the mammoths space?
As a cantrip this makes for some chaotic fodder. Loud noises heard up to 100ft away? Perfect to keep people awake, startle them, create a distraction, scare off animals potentially (if the DM ruled it did), help convince very low intelligence creatures (capable of speech) that you are a supernatural entity, etc.
DND Beyond doesn't clarify that the range is a 5ft radius around yourself.
God I hate this site.
yup
but it is
It is a five foot range. Range is always from a caster, outward. Using a grid, it does not include the box that your character is in because you can not share a grid square and the spell does not affect the caster. The boxes around you, all 8, are 5 feet from you. The far edge of the square next to yours is the 5 ft total distance. You can not hit a creature two boxes away as that starts 5ft 1nch to 10ft. Thunder wave is a different spell with different rules.
"Heard 100 ft away". Doesn't affect you one hundred feet. 5 ft for range.
Total dmg is 8 squares around you. Every Square touching your square.
They are 2 different spells this is a cantrip from xanathars guide to everything
yes
the 100ft is the sound range, not the attack range
OK so there is much confusion what I got from it is th a it's every creature that a can hear the clap form 100 ft away... the range really has nothing to do with it if you're within 100 ft and you can hear the clap yoy roll constitution . But now th a I read I am seeing that the sound is not making the damage it is just saying that the sound it makes can be heard from 100ft away so the damage area is 5ft square centered around the player
With there being no target, the only time the range stat is used is within the effect - so it would be centred on yourself!
