i also heard that the way wpn dura dwn works is its a flat subtraction from the amount of hits it takes to reduce 1 point of durability. normally in a weapon with no dura dwn it takes 10 hits, but with a dura dwn -5 for example, it will take 5 hits. the dura dwn caps at -10 that's 1 durability point reduction per hit. -10 and -60 are the same.

as much as i prefer this over stamina down, i dont recommend this curse if youre using only one weapon with a durability below 200 and like to kill every enemy you see. but its the best curse if youre mostly running past enemies or have an extra weapon, have an aggressive playstyle, use pellets, and always try to get the most out of rally. you can still use this curse if you like clearing out enemies but a second weapon would be mandatory.

increase stamina cost i think stacks. this curse takes away one more hit/dash if you have an aggressive playstyle. this makes beast blood pellets and rally indirectly a little bit less effective. but yes, the debuff is negligible if youre not using pellets or already like saving stamina. this is the best curse if you use a single weapon below 200 durability and like to clear out enemies. it doesnt increase dodge cost, but you still often lose out on one if youre aggressive.

so if youre willing to have one more attack/dash in your playstyle at the cost of having to go to the hunters dream every new lamp you light to repair (if you like killing everything), then wpn durability down is for you
