Choking Horror rune question

[Mr Compassionate]

So I read up that runes DO stack which is awesome but what does that mean for choking horror? If there are 2 choking horror runes stacked, lets say a 56% chance of terrifying more than 2 enemies and a 64% chance of terrifying more than 2 enemies, what does that mean? Will that increase the chance that LOTS of guys will run away or merely increase the chance that more than 2 will run away? Cause I would love to do a Mark of the Ninja style terror mask build but I want know what I am doing when making the build. I already know that terror is a powerful weapon because it basically means that all a chief or captain's guards run away and leave him alone with me but I want to see if I can get the most terror for my buck.

i think the highest value wins the competition here. If you use one medium number rune while terrorising a orc may be enough that all run away but not so if a boss is nearby calling for troops then even they will fight unless you stack up runes as you mentioned but it cant go over 100 percent anyways ! it works to some extend as i start all my attacks on bosses with a terrorise on the guards then i have the boss alone for me to handle most of the time ! Still some have the notice in there profile calls for troops thats where that rune does not fully function in keeping all away! Those that did not see the terrorise you did are not affected and may anyway come to the help! so be prepared .

So I have 2 Choking Horror runes that do 91% chance, is it worth keeping them both on or is the second superfluos?

[Veneratus]

that's not how maths works. all runes stack yes but % chances are not additive. aka.

Favor of the Lady: gain x% health on drain or brand. These runes are additive and having multiple will increase the amount of health gained.

Choking Horror: x% chance to fear more than 2 enemies on drain or brand. These runes are not additive, % chances do not stack they are seperate so while using multiple of the runes will increase your odds it will not make 2 50% runes = 100% chance, it is still 50% chance but you have two chances at that 50% chance, make sense?

And no compassionate it's a waste to use both runes.

When you have same runes with percentages, you can click on the button that says stat summary or whatever on the weapon and it'll show you if they stack or not. I had 5 runes that said "x% increased damage while on mount" so when I had 5 of thoses, I did around 300% more damage while on a caragor.
