Does it stack chancewise? More importantly how long does it put your opponent in knockback animation?

No.

It does not stack and you cannot guarantee a 100% kb.

It is only dependent on monster 'Size'.
Several monster types cannot be Knocked Back.

players = size 2 50% chance

it depends on how much dmg u do..if its 1/12 and u send them to fhr recovery then its kb..i tried it with low kb dmg and high kb dmg...only high dmg allowed kb to work,,this is for pvp though

i have kb'd paladins with a 0% ed fools rare greater taloon : )

maybe it was ur chaos claw that did it..and maybe u hit deadly strike which doubles posion and physical dmg...remember fools claw when equipped gives ar bonus to chaos claw too

trololol

wronk.

knockback will trigger on all melee or ranged weapon attacks at 50% regardless of damage, against other players (size = medium).
FHR will never knockback your opponent, however when you knockback someone they are always placed into FHR

for most attacks, you must deal 1/16 of their HP to do 37.5% chance of fhr
1/8 of their HP to do 75% chance of fhr
1/4 of their HP to do 100% chance of fhr

with some exceptions, notably all throwing weapons, bone spear, and all bow/crossbow attacks, you need to do 2x the damage for the same brackets;
1/8 of their HP for 37.5%
1/4 of their HP for 75%
1/2 of their HP for 100%


with knockback, you will always have a 50% chance of knockbacking + fhr in addition to the chances listed above of just FHR.
