Regarding +damage +crit

[jermsz]

Do these effects from items have any effect on spells? or just melee?

[Phineas]

The crit effects just your regular attack, whether you are a ranged or melee hero. Fun fact, the two images created from Geometer's Bane inherit your hero's critical strike capabilities.

[Darkstrand]

No, they do not effect any spells.

how do crits stack?

[Dux0r]

they stack as following.

If you have a base chance to crit for say 30% then have an item that gives you 15% chance to crit, bot at 2x damage.

You do NOT get 45%.

Afaik the maths behind it are something like 30% chance, if that fails, you get another 15% chance.

Similar with stacking bucklers, its not 60% chance to block damage is 30% x2..

I fail at explaining this, someone else do it :)

[New_guy]

If you have an item with a critical effect, and a skill with critical effect, then You have 2 chances to do critical: a 30% and another 15%.

[duglaw]

and life leach ? melee only or ranged as well ? does it work for any special attacks ? what about cleaves / splash damage ? if you get leach from cleaving a whole creep wave that could be a nice amount of heal.

This is a mathematical problem you're having here.

You have two distinct actions.

The first crit is a 30% chance of occuring. From here on I will call this a proc.

The second crit has a 15% chance of proc.

Now, when combined, your chance for any crit proc'ing is not simply 30+15=45%.

You also must account for the overlap in the two events. So you need to subtract the chance that both crits occur which is .3*.15=.045

So the final chance of any crit occuring is:

.3+.15-.3*.15=.405

A perhaps easier formulation would be this:

Chance of any crit occuring = 1 - (1-c1)*(1-c2)*...*(1-cn)

Where you have n number of chances to crit.

sumed up:

in terms of defense, if you are carrying 2 shields, this will happen:

an attack is done towards you, 4 possible outcomes:

Possible outcome = you get hit
= you block from 1 of the shields
= you block from the other shield
= you block with both shields

so... this means that any hit or shield chance items work INDIVIDUALLY as in: dont stack but rather each has its own proc chance.
