Backstab damage aug question

[PKinternet]

I am not sure if this helps of if it will confuse the matter more, however, I will chime in anyways.

I believe we are mixing two stats.

1) Skill Mod: Backstab +25% ~ To my understanding this affects if the Backstab lands and not the damage. And it only take the highest %. So if you have more than one item with the skill mod only the highest number counts and it is not cumulative.

2) Backstab DMG: +95 ~ This does affect damage and it is cumulative for one slot. This is what Vaion recently changed. So if you have Backstab DMG on your weapon and augs it all adds up and that's what is used to calculate the Backstab Damage.
Even though it now checks the highest value by slot, the chances of a Rog having another item other than the primary weapon with a higher Backstab DMG is very unlikely.
Also I believe the highest Backstab DMG you can currently have is: 322. Donor weapon (65), Both Donor Augs(95,105), Holiday/T9 augs (15,15) and Khasva's Aug(27).

I just ran a couple of parses. The backstab dmg on augs definitely do stack and are combined. When a weapon with combined bs damage 267 is used. max backstab is 143604 (no discs) avg 55864. Backstab damage 65 max bs is 32000, avg 13086. If it was just using the max from the first dagger (105) it wouldn't be that huge a difference versus 65 bs dmg.

Ok now I am lost
Is there a point in trying to collect as many BS bonus as possible ? Like getting Kerani/Burger mask, immaculate band and such ?

[Nilbus]

Not really. The way to maximize BS damage is by getting primary weapon Backstab damage as high as possible. Currently that's the only slot checked. V was trying to get it to check all slots and use the highest value from all the slots, but that wasn't working so was reverted.

Like Galdace said looks like max on one item (with augs) is 322. I'd be frightened if any single slot ever got higher than that. The change V was trying to make would benefit rogues that don't have donor weapon/augs and might have a mask or other slot with a greater backstab DMG mod than their weapon (i'd wager not a super common case)

[Vaion]

Just posting for 100% clarification. The code searches all slots for the item with the highest +backstab damage. This includes augments in that slot as well.

So if your primary has +30 backstab damage and your ring has +15 with two augments that add +30 total, then the code will use the ring slot over the primary when calculating damage.

The code was originally reverted due to a crash that was happening with other changes implemented at the same time, but the crash was fixed and the code to search all slots is live and functioning.

Good to know. Thanks Vaion.

I am looking at various augs and trying to figure out how to best equip my rogue but I am mildy confused as to how the modifiers work.

I assume that if a weapon has 20% to backstab and you have another item that has 18% then you get a total of 20%. How does this work the backstab damage modifiers?

IE does the damage on the donor aug stack with the pristine green ornament and other items or does it just take the highest damage number you have and apply that as it does with skill %, if it does add them together is there a cap?

If i had a donor aug is there any point collecting other items with + backstab damage or am I just wasting my time?

Thanks.

I'm not sure how the new code works and what specific stats it works on as I haven't logged on in a while But to simplify things with my simple understanding (please correct me if I'm wrong...) :

There are several types of backstab stats (don't jump down my throat for using the word 'stats' ).

The most important is backstab dmg, which is listed just under the dmg/delay of the weapon. All augs in the weapon add up on the backstab dmg, and a t8/donor weapon with both donor augs+dsk3 aug can get that backstab damage pretty darn high (though the disparity between donor/end game on this stat is pretty darn high, I won't get into it ).

Then there's +backstab %, which is a skill modifier. Pretty darn important stat, but not as important as the backstab dmg described above. These stats do not stack. Only the highest % is applied.

Then there's the thing most people get confused over. +backstab dmg. This has in the past been listed on a lot of items besides weapons, and people get this stat confused as the backstab damage I first described. The +backstab damage here is listed near HP/mana iirc on an item, and is pretty worthless. It's akin to other +skill dmg stats like +flying kick dmg, +bash dmg, etc. It only adds that number on top of the backstab damage. Pretty early on a rogue will be BSing for 12-32k, so adding +95 damage on top of 32k is like a gnat farting into the wind.
