The actual rarest thing that can happen in Terraria.

Hopefully I didn't fat-finger some numbers here. Chances are high given how much there are...
even if I did, the range of around 10^500 should be accurate no matter what. Does it even matter at this point?

Some people have mentioned possible inconsistencies involving the Mech boss summon calculations which might affect the numbers a bit.
(Mechanical summons may only drop 1 at a time, not all 3.)
I also may have forgot about Lucky Coin extra-coin chances. Oops!

Also, credit to filipssh for the reduced gap design for the hypothetical logic gate thingy.

i actually did this one time

Mathematical chance. Not real world chance, because RNG mechanisms work differently than mathematical "luck". With RNG quirks added, the actual probability would likely be 0, as a lot of those events would probably be mutually exclusive because of the way RNG is programmed.

Happened to my buddy Roy the other day

If luck is calculated on the same tick i dont think it counts, should count the average of all luck possibilities if they all lead to the same outcome

Oh wow didn’t know it was that rare happened to my friend Todd

If you wanna put that number into perspective, think about it like this: million =1, billion =2, trillion=3, quadrillion =4 etc... decilliion= 10 sexagintillion =60. Unsexagintillion= 61, septenseptuagintacentillion= 177 each increase in 1 is multiplied by 1000

Ez

This happened to me

rod of discord is rarer

What

How about killing multile dudes with that one click and them dropping even more?!

i don't know if this counts, but there's a slightly lower chance (1 in 10^690 i think) of waiting 899 ticks between black recluse's web spit attacks. i saw it ages ago when i was trying to find out poison staff rates (i was a noob) and it has lived in my mind rent free ever since. crazy video!

happens to me every playthrough so it cant be that rare..

i like your funny words, magic man.

Oh yeah? My sister has four children and all four (!) of them are male? How likely do you think THAT is!?

To put this number in perspective, the number of atoms in the observable universe is somewhere around 1*10e82

this is actually rarer than finding a girl.

inb4 dream switches to terraria and does this in a 2 and a half our stream
