Earthquake spell issue

Why do 4 level 1 earthquake spells take down walls? They don't do 100% damage. 4*6=24 24*4=96. Furthermore, if 96% damage is enough to take down walls, why don't three lvl 2 spells take down walls? Three lvl 2 spells do the exact same damage as 4 lvl 1 spells. 4*8=32 32*3=96. There is zero logic behind any of this, other than apparently somebody at supercell just randomly deciding that 4 spells is a lot so it should work

Wrong. It operates off remaining hitpoints. You cant add percentages because after the initial spell the damage drastically drops. Basically if the spell does 24% damage to walls the second spell only does 24% damage to the 76% remaining hitpoints. I could go into great detail however this thread was created for that purpose. Take a look as it will give you the information based on hours of gameplay and tons of evidence collected.

So someone went through and did the math and all it proved was that the 4th lvl 1 earthquake spell you drop on a wall does almost 50% damage. It still makes no sense.

Not almost 50%, as when the 4th spell drops, the wall will be at around 17-20% remaining hitpoints. From what it looks, the entire wall collapses at around 20% or slightly lower.

That pretty much sums it up :D

Did you even read the thread i posted? It makes absolutely perfect sense. Read it. It literally spells everything out perfectly.

Yes I read it and it doesn't make sense at all. 3 lvl 2 spells will take a total of almost 69% and not take the wall down. 4 lvl 1 spells only do 66% but do take the walls down. Do the math yourself if you don't believe me

Well, it explains how the spells works perfectly. It doesn't really explain why the 4th level 1 earthquake spell does so much damage (other than 4 appears to be a magic number that will always cause a wall to crumble). I definitely like that feature of the earthquake spell, but the math doesn't entirely make sense. For the math to work either level 4 earthquake should take less than 4 spells or level 1 earthquake should take more than 4.

Lemme help you.


Spell 1 24-100=76
Spell 2 (24%*76=18.24)-76=57.76
Spell 3 (24%*57.76=13.862)-57.76=43.89
Now Spell 4 will drop it BELOW the insta kill damage.You need to remember that the 4th spell is still doing damage, and not just insta-killing the wall.
Spell 4 (24%*43.89=10.53)-43.89=33.35


So more like 33% at which point its at the threshold for insta kill. Remember that the threshold for walls is also 4x that of normal buildings.

3 lvl 2 spells take it lower than 33% bro. 31.44 actually. No matter how you cut the math 3 lvl2 is more damage than 4 lvl 1

This is correct assuming that the only constraints are mathematical. However its generally accepted that a 4 spell multiplier was implemented so that 4 spells must be used regardless of the math. I think what they are doing is testing the waters with the spell to make sure it is balenced and may switch to 3 max quakes in the next update or so. They didnt want to upset the games balence and i guess they figured its better to make the spell more powerful than release it and cause chaos due to a massive upset in the balence (not that i think it would).

Yes but after the second spell the wall still has 46.24 % left. Its 4% higher which is generally assumed to be the reason why the 4th spell is required due to the instakill. Also remember that the instakill point is not defined and might be a floating point, and not fixed.

Right from the linked thread.


What we can conclude till now:

- There seems to be a minimum number of spells for walls to be destroyed. It is 4 based on the above list
- Knock off hit have a damage of 12 - 14% & should be ×4 for it to be able to destroy a wall with 43.9%
- Spell upgrade doesn't affect this ability (at least not positively)


This subject is open to additions, edit and removing where needed. Hope we will get the answer soon and looking forward for you collaboration guys & girls :o


Final Results:

- Knock Down Damage(KDD) is the point at which a building is instantly destroyed by one spell
- KDD is 17.5% for at least lvl1 & lvl2 spells(other levels to be confirmed later)
- You need minimum of 4 spells to take out any level of walls(although on the 3rd spell KDD x 4 can take out wall, this should be a limit made by supercell)
- There is no difference between dropping spells over each other instantly or one by one

So just like with poison, there is no reason to upgrade your earthquake spells. The nominal damage may change, but what it can actually accomplish in game does not.

The only reason to upgrade your earthquake spell is for it to cause more damage on buildings. Otherwise, no matter the level of the spell, it will take the same amount of spells to destroy any level of walls.

The Quake Spell is wrong!

So, when you use the quake spell it takes 4 of them to take down walls, but that's wrong, let me explain.


The Math Behind the quake spell

I am going to be using a lvl 1 quake spell, because the other lvl's dont matter.

Im use people have used the quake spell by now, and that it takes 4 of them to take out walls, but the problem is that this is wrong. The reason this is wrong is because, this is exponential decay, and if you remember from school, whenever something is exponential it will never reach/touch the asymptote, in other words the limit does not exist. It wouldn't take 4 spells to take down walls, it would take an infinite amount of spells, but it still wouldn't take down walls.

Equations:

Y=a(1-b)^x
Y=a(b)^x
a= Hitpoints
b= damage percentage
x= spells used

When I first thought of this I used this equation Y=a(1-b)^x for a few hours I thought that it would take 30-40(I say that because I didn't want to find the exact number) spells to get close to the asymptote/limit (0). I changed equations, I changed to a much simpler one Y=a(b)^x this one got me much closer to the 4 spell target. Here's my math.

(I will be using the hitpoints of a lvl8 wall)
Y=3000(.24)^4 = 9.95328 this means that the will will have 10 hitpoints left, but you say ok just one more quake spell, lets try it.

Y=3000(.24)^5 = 2.38879 ok one more should do the trick

Y=3000(.24)^6 = 0.5733 ok looks like it did the job, not so fast there. Thats half of 1 NOT 0

Y=3000(.24)^7 = 0.137594 still not 0

Y=3000(.24)^8 = 0.0330223 still not 0, but close enough. thats where supercell calls it 0, but really you can keep going forever.

if you were to change this to a lvl 9 wall it would take more spells to get it close to the asymptote/ limit (0)

​Now I don't know calculus, so there could be a better equation out there that can solve this better, that's why i'm using algebraic equations.

The EQ spell stats are not wrong but there was an unclear part but the spell description says it will completely destroy damaged building but the level of damage was not specified. Check link in my signature for more details

Wow! We create troops out of a magical pink or black liquid collected from a never ending underground source and people are trying to explain things with maths, lol

Why did I waste DE upgrading the Quake spell to lvl 3 then? It was completely pointless. Level 1 does the same thing.
