Does backstab talents proc with chainsword special?

[Prince Ian]

What is considered a backstab, and then i see "ranged backstab", that is worded a bit confusing.

[TaKo]

i feel like what it is is self-explanatory

it's just hitting someone from behind, as unreliable as hitboxes can be

i have read that things that proc off of backstabs wont proc unless the backstab multiplier is above 1x(by default only the dagger has a higher than 1x multiplier) meaning you need to take backstabber talent to make other melee weapons trigger stuff like pious cut-throat or ambuscade to make it work with ranged weapons(tho maybe raking fire blessing works too?)

It should be the same no matter what weapon you use, it does not have to be a "stab".

Other than that, the meaning depends on the ability, unfortunately. This is one of those annoying concepts that means something different for different talents/blessings/abilities.

For most abilities, like most talents, and anything that references 'ranged' attacks on the back or 'ranged backstabs' this means something generic. This refers to any attack made on the backside of the enemy hitbox and includes any attack made from behind within about 120-150 degrees.

For a few specific abilities, however, like the "Ruthless Backstab" blessing on knives, a backstab quite literally means a hit on the 'backstab-spot'. This is a weakspot, similar to a headshot, and is located in the exact middle of the rear-portion of an enemy unit's hitbox. It is easiest to think of this 'backstab-spot' like hitting enemies in the "spinal cord" because it tends to be quite narrow. If you hit it correctly, it will give you an orangish hit-indicator that is identical to what happens when you hit an enemy in the head.

So to answer your question directly, for most zealot talents, a chainsword special SHOULD still count as a backstab if it impacts on the back of a model.

backstab is just gameplay jargon for melee attack that hits the back of a enemy...
