Critical/Bash + Arrows

Hi, I have another question about arrows: in Dota games, critical strikes and bashes STACKS with arrows of any type (I mean, I can autocast ice arrows and have critical strikes or bashes too while attacking). I tried putting on a unit both arrows + critical/bash but they didn't stack! I tried also to put on that unit an item with that abilities but it didn't work anyway... Some ideas?

I tested this once, my conclusion was, critical strike always overrides arrow abilities, whenever it fires, the arrow ability doesn't.

I tested it many times before posting, using a 100% chance passive critical strike with poison/flaming/ice/frost arrows ability, but if you cast manually the arrow or autocast it by attacking, the critical strike NEVER fires, even if it has a 100% chance to trigger; my conclusion should be that arrows override strikes.
The strange thing is that during dota games, you can use TOGHETER arrows, critical strikes and bashes and they all fire togheter. What can it be ?

Critical Strikes only occur on ATTACKs. When you manually cast arrow spells, it counts as a spell, not an attack, so it doesn't fire.

Crits and Bash override every orb ability. In DotA they do as well, the difference is that the arrow effect appears to fire, it actually doesnt.

Try it, get Drow with Frost Arrows to crit, the arrow will look like a frost arrow, but it won't actually slow.

They probably triggered bash/crit or arrows to make it stack.

Uhm, it can be that the arrow doesn't slow the target but it only shows the animation, but let's take a look to the Venomancer hero; it has poison passive attack and it can have critical strikes WHILE poisoning the target (u can see actually the poison buff on the target...). The problem is that i tried a lot of times and if u get a normal hero with every type of arrows (flaming, poison etc...) and a 100% critical strike or 100% bash, u can see that the critical strike NEVER fires, it doesn't override arrow; you can try it by yourself opening a standard TFT map, putting a POTM on the middle and giving her a 100% critical strike; test the map and you'll see that it is so. Can it be a WE option (i took a look to ALL the constants but there is not such a thing)? Thanks.

I don't think that they could trigger a different crit or bash for every hero in the game... Buriza it's just a normal object with a critical strike ability... Thanks.

Ok, i made a sequence with pictures:


Here you can see that my POTM has a 100% Critical Strike!


It works!


With flaming arrows ON, it doesn't work no more...

If they do actually stack and work correctly together in DOTA, then ither the arrows or bash / critical strike have been triggerd. (its not that hard to do... especially for the arrow abilitys)

OMG, I solved the problem! It's a so stupid thing ! The fact depends on the order in which you learn the abilities! The ability you learn last is the one that overrides the others! If you have flaming arrows and critical strike, but you learn flaming arrows first and then critical, then critical will override arrows...

Oh, you mean diff abilities on the same unit, i thought we were talking about items. Item crits override learned orb effects.

Veno's poison also isn't an Orb effect, it stacks with a few items, i believe Mask does, or did, stack with it, and i know Sange stacks.

Yes, its well known, have none of you ever known this before?

The last passive (or autocasted) ability learnt overides the first 1s.

I found i table which i attached to this post that shows which effects overide which effects, and ofcourse, when 2 abilities have the same effects like critical strike, you should use the formula ( 1 - ( 1 - A ) * ( 1 - B ) ), A and B are 2 chances to evade or critical strike, or bash.
Say A represents 15% chance to bash, and B represents 25% chance to bash, it would work out like this:
1 - ( 1 - 0.15 ) * ( 1 - 0.25 ) = 0.3625 = 36.25% chance.
