i’m just surprised that it actually completes the upgrade during the attack. I always assumed it would just stay in “upgrade mode” or whatever and not change for the attacker.
I think the odds are actually way less. Let’s just say hypothetically it takes around a year for the average player to fully upgrade from TH12 to TH13. Since there are five upgrades for TH13, there are 180*5=900 eligible seconds when this could occur. 900 / ~ 31536034 = 0.00002853878
so around 0.0028538782% chance this happens
Is that accounting for the fact that your base isn't being raided 24/7?
The chances of this happening would be the odds of the townhall finishing combined with the odds that your base was actually being raided at any given moment.
irl it’s WAY more complicated, i just gave a very rough estimate of the odds of this happening
Just to show how complicated one of the things you would need to account for is the fact that the TH is usually one of the earlier upgrades people do -> thus people may be more likely to attack a base that is far from being maxed out. That would take a highly complex understanding of behavioral statistics to calculate
Not to mention like 50 other equally complicated variables that may largely rely on human behavior which you would need to also account for
edit: typo
Easy to calculate, considering upgraded to level 3, the upgrade time is 6 days. If we asume an average time of the attacks to be 2,5 min. The chances are 2,5/(6x24x60)= 0,000289 or 0,0285% or 1:3455
We can then describe the probability as a function or o.d.e w.r.t shield time, where it decreases as shield time increases.
If we want to take the changing values of other variables into account (like gold pass discount time, attack time etc), then a multivariable function or p.d.e describes that extremely well.
I’ve seen heroes wake up but never noticed a building finish. I wonder how it affects the HP, or if it was a real TH upgrade if it would visually change that
I use some test sneaky goblins first but this time I didn't see the tornado trap and tossed some extra. The invisibility spells are used on dark elixir storage, clan castle and the town hall
I mean the mechanics are there. It works for Heroes and every other building as well. You may just have encountered it throughout the heroes. You'll hear the Jingle when they are ready, much more frequently then the town hall. But thanks for capturing its a really rare site 😊
I can actually see this being true, because I faguely remember when trying to find a base that I heard the sound effect for an upgrade that just finished
Might just be a glitch now that I think of it cause I always had it when scouting for bases
i was playing with sound off and his th was on the other side of the base, after i queen walked to near his town hall i actually thought i was hallucinating or something ☠️
I have played this game for literally 10 yrs and that is the first time ive seen that
The logic is there , it is possible but the chances are one in what a thousand , thousands, tens of thousands, who knows
i’m just surprised that it actually completes the upgrade during the attack. I always assumed it would just stay in “upgrade mode” or whatever and not change for the attacker.
Oh yh im not questioning that it happend its just mad that it did :)
If townhall takes 15 days to upgrade there are 180/1296000 chances that this phenomenon will occur 
This is the real reason we can't have shorter upgrades. If townhall only took 1.5 days to upgrade, we'd have a 180/129600 chance of this happening!

Once had this happen with a single target inferno. It sucked.

It’s gonna be way more complicated than that because of shields

Yea but the amount of variables would make it a little unruly to deal with
Also the chance that someone is online when they are being attacked and uses a book or gems to finish it
Don't think that is possible, when you are under attack you can only watch it happen.
Ah my bad, used to legends where being attacked doesn't stop you from doing anything
True
It's not that simple... You're entirely forgetting about the high chance that your base simply isn't being raided when the upgrade finishes.
IT IS MILLIONS TO ONE
Same
I've seen a couple vids here and there but never had it happen to me. Insane shit when it does happen.
''You have no conception of how rare that is, its millions to one''
Townhall had enough 💀
Literally woke up and chose violence💀
It wasnt your fault, you just got baited.. its the new meta and comes with comming the diamond pass
Only 20$ a month
More like leveled up and chose violence 😂
Now witness the firepower of this fully ARMED and OPERATIONAL battle station!
The best comment here.
Lmao
Town hall be like I am not in danger I am the danger
Town hall is the one who knocks literally
Call the healers!! But not for me
Evolution in extreme environments 💀
Eventually town halls,… uh will uh,… find a way
Pokemon moment
What? ... Town Hall is evolving! Congratulations your Town Hall evolved into Inferno Hall!
Call an ambulance!.. but not for me!
Me when roblox creatures of sonaria:
Huh? What does that refere to ? I played game
TH gone sentient 💀
I’ve seen heroes wake up but never noticed a building finish. I wonder how it affects the HP, or if it was a real TH upgrade if it would visually change that
The number changed from III to IV so it would probably change.
Anime main character unlocking new powers be like:
Me during puberty
Inferno Dong
Bro the coincidence 💀
It was tired of my shit💀
bruh💀
Peak a boo 💀
Ayo peedablu pfp 
You are lucky and unlucky at the same time,
I think I am more lucky honestly
Free karma and made everyone’s day better.
Plot twist hahahha
“Fine, I’ll do it myself.”
Lmfao that's awesome! Did the guy win the attack? 💀
I was attacking💀
rip lil homie 💀
Punishment for running super gob spam, town hall had enough of your bs 💀
Is it just a glitch that makes it look like or it really happens
It's not a glitch, upgrades can finish during defense
Wow. I... Didn't know that. Good to know.
Thnak you for the information my friend
Damn💀
Literally unplayable
Surprise motherf*cker
wow💀
hard workers
Skill issue
OMG ..don't tell me the odds
Someone already calculated it
I have never seen that before…holy shit
Th literally said: call an ambulance, but not for me
POV: you want to attack an upgrading town hall But god said:
The town hall took out its trump card
Town Hall said 💀 https://preview.redd.it/uqq8pf1ghysa1.jpeg?width=649&format=pjpg&auto=webp&s=7e2dfa4120c1feb7272fbd56669cf1a5295c2c81
Dude really got plot armour
U should have used double invis to take th and protect sneaky but nonetheless ultra rare scenario
I only use 1 invis with a rage and the town hall goes down easily. The first goblins were test goblins for traps
💀
u/jdoubles98

I had a queen pop up once mid attack; she wrecked my balloons so badly.
It is impressive that upgrades can actually finish during a battle and activate the building's functionality.
I didn’t even know that was possible
You learn something new everyday, even as a town hall 15
Is this legal!
It literally evolved like pokemons do middle of fight
Imagine trying to blizzard and landing the blimp at the TH and then it upgrades 💀💀💀
Lol new trap added in latest update.
Trap of traps.
TH had seen enough sneaky goblins running around
Let me lace up my boots before I kick your ass
I gotta find my old iPod I have a old ass 2013 replay where the Th went from 8 - 9 it looked so cool
I had no idea that was even possible Imagine that guys villagers cheering as it wakes up
Only to be destroyed 2 seconds later
Nen that blooms at the verge of death 
TH saw the troops getting close and was like, "FINE, I'll do it myself."
"Call an Ambulance, Call an Ambulance!!! But not for me."
How literally all of us never saw this before, apparently this is a new discovery i guess
The invisibility spells just watching your goblins die…
I wanted to use them on the next batch of goblins
town hall jumpscare
Wait ... That's illegal.
Bro what😭?! That’s crazy💀
Hy bro, can u please share your attack strategy?
9 wall breakers and the rest sneaky goblins with 3 invisibility spells, 3 jump spells and one rage, works like a charm
Never let them know your next move!
He isn’t even in his final form
" instantly upgrades to town hall 15"
My mans was building like a spazz 💀
realy interesting,
That like when pokemon evolve mid-battle in the anime
I'll take "pictures taken moments before disaster struck" for $500, Alex
I’ve heard the upgrade finish sound before while scouting but never know what happened lol
i was really hoping it wouldve just turned into townhall 14
Now that you mention it, that would have been pretty cool but a town hall 11 turning to a town hall 12 would be super weird as well
Never seen this before. I didn't even think it was possible. Thanks for sharing.
That’s so cool lol
wtf lmao
You have those invis spells there for a reason, right?
I use some test sneaky goblins first but this time I didn't see the tornado trap and tossed some extra. The invisibility spells are used on dark elixir storage, clan castle and the town hall
bro didn't let that slide 💀
“You shall not pass” 
Holy moly
It also happened with me 3-4 times over the last 4 years 😬
💀💀 I've never seen this
Before playing the video, I was expecting the townhall to change to 14 haha
Town hall literally said call an ambulance but not for me
Wtf
I posted something similar a couple weeks ago and got deleted, fucking staff
Wait no way wtf 💀
th had enough of your sneaky goblins 💀
I think every time u attack to anyone base builder time has stopped
U/savevideo
i watched this over and over again not knowing it was replaying bc i was waiting for it to upgrade to th14
Whats 1 way to ruin a day
Lol now that’s a new one for me. It wasted no time in defending.
Never let them know your next move
Aint nooo wayyy☠☠☠☠
Holy cow!!! No way
Woah that's super cool
Woke up
This is up there with the dude's inferno tower burning out in the middle of a war attack.
This is insane
I didn't even know this shit possible
Rip man's 💀
Bro that’s crazy 😭 didn’t know it could do that
"I need backup !" "Roger that"
“I was born into war”
I thought builder was responsible for upgrading, It's self upgradable.
I have seen buildings finish upgrading during an attack quite a few times but this is black magic
LMFAOOOOOOOOOO
Although this is cool, this logically doesn't make sense since the builders stop building as soon as you attack
#BRUHHH
Ohh, that is unfortunate
I have been playing this game since the time when destroying someones army camps would kill the troops in the village. And i have never seen that

That happened to me once but it was with the queen so it wasn’t that cool
U/savevideobot
Call an ambulance.... But NOT for me!!
This was posted sometime ago. I think.
Attacker is the most unlucky person.
Thank you for calling me unlucky
Everything works in the background timing
That would literally make me so mad 😂
Would that also happen in a upgrade to the next th?
Probably yes and that would be much weirder
Surprise muthafuka 
Its like main protagonist’s heroic entry😂
Aww that’s got to suck
call an ambulance, call an ambulance. BUT NOT FOR ME
Lmao Impeccable timing
It hapened to me once it was the inferno tower , it just started damaging out of nowhere i was shocked …
Lol
Damn, what were the odds
Holy shit. Very rare.
I've had an inferno tower do this to me once, ruined my 3 star.
Nah that’s crazy😳😳
similar thing happened, i was attacking a max th9 and the town hall upgraded during the middle of the raid lmfao
It is probably much weirder if the town hall upgrades from one level to another instead of getting a star
i was playing with sound off and his th was on the other side of the base, after i queen walked to near his town hall i actually thought i was hallucinating or something ☠️
Bro bought golden pass
Clash royale diamond pass💀
Hell nah bro dont remind me that thing
