I think I will be keeping Backstab on this Rogue anyway (was wondering whether to cash it in for Vicious Fighting, but 55% hit to crit sounds like enough), so in which case the top end of the damage on a Deathblows Backstab crit will be 266-381 before DR, so I think that's pretty fun. I may well take Nightshroud instead of Tidefall for 3 Shadowing Beyonds per rest, so that'd give a lot of these punchy hits in a tricky encounter. Plus, it's using the Rogue as was advertised by the devs, even if the implementation of Rogues does make using them as advertised difficult.
You also get two Backstab attacks (if you didn't notice): the first hit AND the second hit will receive the backstab bonus. Recovery time doesn't matter and it also doesn't matter if you carry a two hander or a single weapon or if you are dual wielding. You will always do TWO backstabs - as long as those are auto attacks. When using an active ability you only get the backstab bonus for the first hit (also when doing a Full Attack).
You don't even need to be stealthed when striking. It's only important that you commend the attack from stealth. If you don't "recommand" while the rogue is running towards the target you get the bonus. This makes it possible to deliver backstab even with 0 stealth points. But it's way easier to pump stelath and just stand in the first or secoond row and let the enemy approach while you remain unseen - and then just simply attack once they are near. Also: Backstabs from the second row with a reach weapon are very comfy.
So... Backstab is worth it in my opinion. Especially if you also use Shadowing Beyond and the Cape of the Master Mystic.
Both reasons are pretty poor to be honest. What I was expecting was that all the Rogue damage mods would add together and then multiply the "damage" listed, seeing as that would be the most literal interpretation of their tooltip. It's things like this that really get under my skin, accurate tooltip descriptions should be a given and imply laziness on the devs' behalf. I've seen people call them out for it on the Deadfire subforums, so hopefully they'll have learnt their lesson, we'll wait and see.
That was me (amongst others).
I really love PoE - but that was and still is my no. 1 criticism. Bad, really bad explanation of game mechanics.
