Ar you saying you have tested those two sets together and they reduce your sprint cost to zero? If so, I would say that is not WAI. The thing about additive bonuses is they can break things if you can stack them. Multiplicative bonuses behave much nicer. What I would expect from a 100% reduction is halving the normal value if you have a single 100% reduction. As you add more, according to my toying with a calculator, it converges to a .3678 multiplier, or 1/e. Two 50% percent reductions should be a .4444 multiplier.

Ofc there's many ways the could do it... I would probably add up all the reductions, call it X, and plug that into (1+X/100)^(-1) where X is the sum of the percent reductions.

For anyone who's curious, the equation that converged to 1/e was (1+1/X)^(-X), though it probably isn't that surprising.

Fiords + Darkstride = 100%

NO STAMINA LOSS WHILE SPRINTING!!!

Can you confirm you meant Fiords + Darkstride (65%) instead of Prisoner + Darkstride (100%)? The latter makes sense to remove sprint cost entirely but not the former. Testing I just did doesn't give me 0% sprint cost with Fiords + Darkstride (confirmed).

The formula I verified around update 10 for sprint cost was:

SprintCost = Base * CP * Buff * Set * Item

So sprint cost modifiers stack multiplicatively in the 4 categories and additively within a category (i.e., DarkStride + Prisoner = 50% + 50% = 100%). This seems to match my quick testing I just did on live:

• Base @ CP160 = 546 Stamina(confirmed)
• Darkstride = 273 Stamina (confirmed)
• Darkstride + Fiord + 7% Well-Fitted = 177 Stamina (178 in-game)
• Darkstride + Prisoner = 0% (confirmed)
• Your Initial Case = 127 Stamina (theory)

So everything seems to match the theoretical formula unless someone can find a specific case that does not. I also happened to come across a strange bug with weapon swapping and the Fiord set:

• x5 Darkstride (Shield, Boots, Belt, Shoulders, Guards)
• x5 Fiord (Necklace, Ring, Helmet, Chest, Bracers)
• Sprint Cost = 177 as expected
• Swap to other weapon bar with no Darkstride (so x4 Darkstride)
• Sprint Cost = 432 as expected
• Swap back to original bar
• Sprint Cost = 219 stamina (177 expected)
• Unequip and re-equip any Fiord item (re-equiping a Darkstride item does nothing)
• Sprint Cost = 177 as expected

I'm unsure why the Fiord set breaks even through it is Darkstride on my weapon bar...strange. Perhaps double-check if that is the case in your setup. It looks like initially Fiord + Darkstride work additively as expected (15 + 50% = 65%) but after the bar switch they switch to working multiplicatively (0.15 x 0.50 = 0.75) until you re-equip a Fiord item. Also this only appears to happen with Darkstride items in your weapon slots. Fiord weapons seems to work fine and don't have this issue when weapon swapping. It also happens with Prisoner + Darkstride weapons.

Update: I've confirmed that Prisoner + Darkstride gives you 0% sprint cost in-game.
Update: More detail on the Darkstride weapon swap issue.
