What is the rarest thing that could happen in Terraria?

Some things that would make this A LOT more rare

dropping hallowed biome key (1/2.5)
dropping from a zombie (slimed zombies can drop slime staff with same odds as a regular slime) (1/10k),
slimed zombie is of the largest size (1/22)
also getting a zombie arm (1/250)
also getting a shackle (1/50)
also getting a spiffo plush (1/1.5k)
also getting bloody machette (1/2500)
also getting mechanical worm (1/2500)
getting ruthless on slime staff (1/40)
getting warding on shackle (1/20ish)
getting legendary on zombie arm (1/40)
getting demonic on bloody machette (1/40)
instead of getting a crit with 4% crit chance, getting not a crit with 99% crit chance (1/100)

all you would loose out on is 13 copper ore odds

why the slime staff isn't craftable is honestly beyond me
would make the early game summoner less of a pain in the ass compared to farming flinx's or the jungle with your coppershortsword, or getting luckey with the slime or finch staff

Dream be like: "I swear I didn't cheat guys"

Yo this happened to me yesterday😵‍💫

now, lets add a second slime

i could get this

this happened to my friend dave once

I started mastermode world
1 day: spiffo's toy and slime staff
2 day: zephyr fish and the dirtiest block
How?!

could have made it even rarer by having it be a balloon slime that dies to a falling star on the day of a new moon. the more conditional statements, the rarer; a green balloon slime killed by a falling star during the night of a new moon while it’s raining that drops a mythical slime staff and exactly 1 silver and 69 copper coins upon it’s death. Can’t be bothered calculating but basically the more conditional statements, the lower the probability, regardless of the probability of the conditions on their own; sure the phase of the moon doesn’t matter, but the chance of it happening during a new moon is less likely than that of it happening during all of the moon phases and lower is what we’re going for.

Time to grind i guess

you forgot to add "while your wearing socks" chance

Dream can do it first try

now kill it with a zapinator while getting every effect at once

i got some map that summons the pirate raid from slime

I was playing with a friend joking about the dirtiest block and about an hour later decided to double our basement and got one, our house was at spawn and the playthrough sadly ended shortly after so that was really cool of a find

what about the 1/24 (4.17%) chance of receiving two mana stars when not at max mana?

this happened to me

I once got a tabi and black belt from the same bone lee, and they even both had the same reforge. This was in calamity though idk if they buffed the drop rates.

Oh dude this literally just happened to me

I can’t lie I’ve gotten 2 slime staffs in my 270 hours by accident and the dirteast block

this is the definition of defy all odds

This happened to me the other day

i heard somewhere that a pirate can drop all of its drops at once so like is that rarer?

Bro this happened to me

yoo that’s crazy just had this happen to me yesterday was soo fire 😍😍🔥🔥🔥🔥

I guess it was pretty lucky when this exact thing happened to me the other day

You guys might not believe me, but this happened. No I can’t prove it.

When a falling star kills a mob, is the drop rate tied to your character or is every star technically it's own npc?

I did this once but I didn't record it

Still more likely then someone beating FTW in master mode not in journey mode with only a wooden sword and the default HP.

I once got the slime staff two times in an hour. And 3 times that very month.

We had a solar Eclipse, bloodmoon and after that a Goblin Army. That was the rarest for us.

Dream: BET

I think I did this

This exact occurrence happened to me

Yeah this might take Dream a few attempts

What if you did all that but killed the slime with a pickaxe, while simultaneously breaking the dirtiest block.

Idk how rare this is but I’m one of my worlds, a meteor dropped on a sky island. Do you know the chance of that happening is.

i started playing terraria again a week or two ago and somehow got a sugar glider pet within five trees

What? How is this rare. This happened to me like 2 days ago wtf! Your lying.

you could use the 1 million damage the zapinator can do!

So you're telling me there's a chance...

this litterly happened to me this morning but ok

This happened to my buddy Eric.

Me when i got the funny slime staff instead of wining a lottery.

You may be able to achieve a lower probability result with a specific set of items from the travelling merchant being sold at the same time

but this is nothing? this is like saying ''what are the chances of killing a slime and an asteroid hitting your house at the same time irl'' the correlation doesnt mean anything??

That happened to me

Ok but what if with that same weapon you killed multiple slimes at once

happened to me yesterday lmao
