Passive: Gain 10 weapon power for every 160 weapon damage done to enemy heroes +5/10 (Melee/Ranged) damage needed for each stack thereafter. 25 stacks max. Decays 3 stacks per second after you've stopped stacking for 2.5s.

Tip: Very weak at first, but becomes extremely powerful over the course of long battles.

Breaking Point cannot shred armor. It just increases the weapon damage you deal as you damage the enemy more and more. It's in the item description. And it only stacks on HEROES.

This item is weak. Get another sorrow blade or a bone saw in place of this. The only time this is better than a sorrow blade is if you need more attack speed and already have another item that grants attack speed. You need 15 stacks for this item to equal the base damage you would get from a sorrowblade, by the time you build enough stacks to outdamage a sorrowblade you will have dealt close to 2k damge. Most battles will be over by this time and your stacks will decay. The additional sorrowblade is a much better choice, don't waste a spot and gold on this.

I love and hate this item at the same time. Main reason I hate it is that the passive is only effective against enemy heroes, which is also why I love it. Getting more than a couple stacks is pretty hard to pull off, and usually this item is not effective unless you can go into extended duels

No, it does not do anything (except for 40% attack speed) unless you are in a fight. If you are attacking an enemy hero, then you get stacks which make you stronger, but for every second you are not attacking an enemy hero, you lose those stacks, returning you to your normal attack power.

I bought another breaking point accidently and was wondering if anyone can tell me if the stats and passive stack?

no passive skills stack but the stats below the passive description do stack for example Breaking Point gives 40% attack speed and that stat will continue to stack with every Breaking Point but the 5% crit will not

You get +15 weapon power, 5% critical chance and damage per second (or per stack). If BP went to 20 stacks, this is the result.

(Note that I will be focusing on a lvl. 12 Krul)

A lvl. 12 Krul has 154 weapon power, 0% critical chance but 50% critical damage.

A BP stack has +15 weapon power, and +5% critical chance and damage.

Note that I will focus on critical hits on this one.

1 stack: 5% critical chance, 55% critical damage, 169 weapon power = 262 dmg.

2 stacks: 10% critical chance, 60% critical damage, 184 weapon power = 294 dmg.

3 stacks: 15% critical chance, 65% critical damage, 199 weapon power = 328 dmg.

4 stacks: 20% critical chance, 70% critical damage, 214 weapon power = 364 dmg.

5 stacks: 25% critical chance, 75% critical damage, 229 weapon power = 401 dmg.

6 stacks: 30% critical chance, 80% critical damage, 244 weapon power = 439 dmg.

7 stacks: 35% critical chance, 85% critical damage, 259 weapon power = 479 dmg.

8 stacks: 40% critical chance, 90% critical damage, 274 weapon power = 521 dmg.

9 stacks: 45% critical chance, 95% critical damage, 289 weapon power = 564 dmg.

10 stacks: 50% critical chance, 100% critical damage, 304 weapon power = 608 dmg.

11 stacks: 55% critical chance, 105% critical damage, 319 weapon power = 654 dmg.

12 stacks: 60% critical chance, 110% critical damage, 334 weapon power = 701 dmg.

13 stacks: 65% critical chance, 115% critical damage, 349 weapon power = 750 dmg.

14 stacks: 70% critical chance, 120% critical damage, 364 weapon power = 801 dmg.

15 stacks: 75% critical chance, 125% critical damage, 379 weapon power = 853 dmg.

16 stacks: 80% critical chance, 130% critical damage, 394 weapon power = 906 dmg.

17 stacks: 85% critical chance, 135% critical damage, 409 weapon power = 961 dmg.

18 stacks: 90% critical chance, 140% critical damage, 424 weapon power = 1,018 dmg.

19 stacks: 95% critical chance, 145% critical damage, 439 weapon power = 1,076 dmg.

20 stacks: 100% critical chance, 150% critical danage, 454 weapon power = 1,135 dmg.

No, it does not do anything (except for 40% attack speed) unless you are in a fight. If you are attacking an enemy hero, then you get stacks which make you stronger, but for every second you are not attacking an enemy hero, you lose those stacks, returning you to your normal attack power.

The stats do stack, but the passive's don't. Passives never stack on any item :)
