A Question about Keywords

[Chadiwan Kenobi]

What is the difference between rending and brittleness?

And do chain weapons' special saw attacks count as multiple instances of damage that could each apply rending/brittleness (whichever it is) via the vet passive (I forget the name, but it's on the right side near the keystones)?

Rending is essentially armour piercing damage, it only affects your attack.
Brittleness is essentially an anti-armor debuff when you hit an enemy that helps you AND your team.

My understanding is that rending is something on your end, while brittleness is a debuff that is applied to the enemy NPC, and affects all incoming damage.

Thanks. When both debuffs are present, do they apply multiplicatively?

Rending isn't a debuff. Rending gives you a % armor piercing. But yes, the effects stack.

Rending increases your damage vs armored (so it negates the armor damage reduction). Brittleness removes by each stack the armor from the hit part of the enemy body. You can see it in psycanium. If you hit crusher with it its armor goes from Carapace to Flak, if you hit it again it goes from flak to unarmored.
Personaly i think rending is just better as you want to kill the target via weak spot idealy on one hit or as few hits as possible.

*Sorry i overlooked your second question. I do not use rending or brittle on chain sword (enviscerator) as it self has armor penetration. I do build it with cleave (Wrath or Savage Sweep) and and + damage with Rampage to make it ultimate horde slayer machine.
I do not have experience with chain axes.

Thanks for the explanations. I was asking because I use brittleness on a Trauma staff to mass debuff armoured units for 5s, and then I swap to a force sword for cleanup. I just wasn't sure what exactly brittleness does.

I do not understand why even use such stupid and misleading wording?
Why not just armor ignore or armor break?

Just 1 and iirc only last hit of the special attack counts as 'hit' in terms of appling procs 'on hit'

Thanks.

It makes for more variety in buff/debuffs, I guess. I just wish they had a menu you could scroll through to read all the keywords and their explanations.

For immersion that it sets within the 40k lore. Same as Dark Souls use of "old english" (Elizabethan english).
If you need to help with explanation about any weapos stats you can refer to those 2 guides:

It's like others said. Brittleness is a debuff on the enemy, Rending is a buff on yourself. But they both add armor penetration. Brittleness also does NOT benefit warp damage, so for example a Trauma with Rending Shockwave doesn't gain anything from it, but the rest of your team or indeed at least the physical attacks with your Force Swords do.

I haven't tested Rending myself, but back around spring/summer I did run tests on Brittleness. Based on the tests then it caps at 80%, lasts for 5s per each application of the debuff. I also remember that back then Boltguns with max brittleness added a little over +250% dmg. So if you normally did say 200 dmg per shot, with 80% Brittleness you would instead do 700 per shot. But obviously this depends on the weapon, and something like lasguns that normally do 2-5 dmg per shot would instead go up to hundreds.
