Well, Rage supposedly stacks with backstabs and guerilla for extra damage
Literally posted in this very thread:
I just tested as a sanity check, and I can confirm this is 100% false. You cannot also crit on a Backstab.
Also, just a reminder that Guerrilla is AP-inefficient. Sneak costs 1 AP to use during combat, so the +50% damage modifier Guerrilla adds is only worth using over a regular attack (costing 1 or 2 AP) if you're entering a fight with a sneak attack, or are using a skill like Snipe or Mortal Blow which already have inherent massive bonuses to damage when sneaking.
I know you posted that: I was counter it with the fact that others have stated and tested otherwise. Don't look at me *shrug* I could care less. I'm neither defending it or not
Also, me and you have done the whole AP economy of guerilla back and forth many times. We've also done it on one handed vs dual wielding for rogues
You -> doesn't add enough damage and is only marginally useful on dual wielding
Me -> for players that sneak a lot in combat it becomes free extra damage cause guerilla isn't the focus on sneaking but a side benefit, thus no reason to not have it. And it price every turn
You -> why so much sneaking instead of attacking?
Me -> avoid detection and out maneuver AI
You -> they'll fix that
Me -> they will, but it should only make it so that someone must actually heavily invest in the damn stat to do what we currently can with one point in it
/semi-rant done
:P just didn't want to give ya the last word.
Also, Limz is kind of arrogant but I'm pretty sure he does it on purpose since he enjoys forum battles

All Hail The God Emperor Limz!!!
Rage really just shouldn't be so universally good. Honestly, it should be made to serve a niche and then left alone
Removing auto Crit from it and making a decent Crit mult. and Crit chance boost along with having it make the user very vulnerable is my proposal
