"You can dismiss such an effect as an action" so it doesn't have to be a full minute. A full minute unless dismissed.

Especially those who are skilled in intimidate

hello

Does the "Make your voice 3 times as loud" Thing make the decimal value 3 times as much, if so, your voice could literally kill people by the sheer volume, its literally the same volume as a nuke at point blank

You get access to this spell with other classes using Strixhaven

Up to 1 minuted, dismiss at will... seems pretty accurate to me, as that means less than a minute is possible. 

Step one get a few friends

step two send said friends to an elderly couples home to tell the couple their house needs exorcising

step three conveniently case this while hidden away near by and watch as the couple agree to all terms and conditions 

step four profit

Oh. Apparently there's a cleric version of Druidcraft.

So warlocks can't use it? Even if I am the race??

Having this and control flames to attach to either the enemy or onto a party members melee weapon within range is something I want to try out.

Not sure if the 3dB ‘trading effect’ would be in effect here, in that for every 3 dB the sound level increases the impact on hearing health which is doubled. For example, 63 dB(A) is twice as noisy as 60 dB(A). The relevance of this is apparent when considering exposure to hazardous level of noise. For every 3dB the noise level increases, the exposure time must be halved to keep the worker safe from harm.

If not: Levels Of Noise In Decibels (dB) Level Comparison Chart - Sound Proofing Guide

Standard talking voice: Between 55 and 65 dB, A whisper is about 30 dB, normal conversation is about 60 dB. (Per USA CDC: What Noises Cause Hearing Loss? | NCEH | CDC)

Level 2 (or doubling it): 110-130

Level 3 (tripling it): 165-195

Shockwave (Sharn: City of Towers, p. 168)
Evocation [Force]
Level: Sorcerer 3, Wizard 3,
Components: V, S, M,
Casting Time: 1 standard action
Range: Close (25 ft. + 5 ft./2 levels)
Area: 20-ft.-radius burst
Duration: Instantaneous
Saving Throw: Fortitude partial
Spell Resistance: Yes
Even if a battle is for a just cause, using fireball on a crowded city street places innocents at risk. The shockwave spell creates a burst of concussive force that disorients victims without causing any permanent damage, dealing 1d4 points of nonlethal damage per caster level (maximum 10d4) to every creature within the area and dazes them for 1 round. A successful Fortitude save reduces the damage by half and negates the dazed effect. The shockwave has no effect on nonliving creatures or objects. Creatures that are immune to nonlethal damage cannot be dazed by the spell.

Material Component: A small crystal sphere.

Remember, a cleric has spellcasting feat, you can use a holy symbol as a spellcasting focus.

3db is not twice as noisy. It is twice as much energy. Twice as noisy depends on the listener and the sensitivity of their hearing, but is commonly about 10db. So the 3x volume means adding about 16-17db to the volume of a sound. The bel (or, more commonly, decibel) is an exponential scale - each 3db is double the energy of the last 3db, each 10db is double the volume of the last 10db, and so on. So 20db is 4x the volume, 30db is 8x the volume, and so on.

The concept is rather easily verifiable, since, for loud volume, you can have headphones at about 0.016w for one person, but you need about 100w speakers to get the same volume for a group of like 20 people, and about 10,000w of speakers for 500 people. It’s also verifiable per your own source - it says “painful. 32 times as loud as 70db” pretty close to 120db. 120-70=50, 50/10=5, 2^5 (aka doubling the volume 5 times) =32, or 32x the volume.

So thaumaturgy can make a noise painful, but only in such cases where the noise was already very loud to begin with. A thunderclap could become an air raid siren, for example.

It also depends heavily on the distance from the source of the noise. Decibel levels are generally measured as acoustic energy, 1 meter from the source. If you were using your own voice to try and deafen a group of people, you would blow out your own eardrums LONG before you hurt anyone else, as your ears, being only about 4-6 inches from your mouth, would get hit with a much larger amount of energy than the measured db level implies, while anyone standing farther away than 1m would get much less energy.

Thanks for the link as it was a interesting read.

This is also a Tiefling trait. 

How do you pronounce this???

any dm will let you do this.

can you use it on someone else not yourself?

As others have stated, how is this not automatically added to teifling’s known cantrips?
