# I finally do the maths on armour break.

I have decided that it’s no longer worth waiting to see just how potent armour break/armour up effects are by comparing with other champions to gain a rough idea, I’m doing the maths.

For these calculations I used my 4* r3 groot as he had some very easy numbers to work with.

Above are the numbers. From these we can see that 284 armour rating=12.4% damage reduction.

We can then do the maths and round up to 286 for a 12.5% (1/8th) of a damage reduction (284= 12.4x22.9 so 286= 12.5x22.9)

Multiply this figure by 8 and we get 2288 or a 100% damage reduction.

So an armour break reducing armour rating by 2444 (r5/50 4* Medusa) increases damage by 114%

Or an armour break reducing armour by 2100 (5/65 5* sorcerer supreme) increases damage taken by 87.9%

To work out the potency of armour break take 2288, now is the armour break (AB) higher or lower than 2288.

If higher: AB-2288=? 2288/?= % over

100+%over= potency of armour break %

If lower: 2288-AB=? 2288/?=% under

100-%under= potency of armour break %

Same calculations apply to armour ups

1,242★★★But there's no longer anything like negative armour if I recall since the 12.0 changes if that's what you're trying to explain

959★★★1,394★★★★590★★★Like I look at blades base crit being 628

WTF does that even mean?

Apparently it makes it be 23%

But his sp2 grants him 2100 additional crit rate

Which means what?!?!?

The numbers in the OP were relaxing

1,394★★★★65★Four Words: your calculations are wrong
