item_poisonlengthresist

and should be capped at 75%.

No, the item_poisonlengthresist is defined in the ItemStatCost.txt file to have possible range of 235 to -20 (Save Bits=8, Save Add=20). This effect on items is to normally adjust the players hidden stat of poisonlengthresist. Since there are no provisions in the game to effect this stat except through the items or active skills, there was no reason to list out any save data parameters for it. It is the poisonlengthresist that has the cap of 75% on it.

I suspect that the skill (or aura state) itself is just using the stored value of item_poisonlengthresist to hold the amount of reduction to do. It will then just copy that value over to the other appropriate values to apply the reductions. To see just what is going on would involve digging into the game with a debugger while running.
