Does Passive MS Stack For New Patch?
What does MS stand for?
Last i checked no speed buffs stacked at all, quickening thirst did not stack with the signet. The 15% for main hand and the 10% for off hand do not stack together, swiftness with the signet will not make you run faster as a whole. This was tested some time ago and I have not retested them all today as of yet but I highly doubt they will stack because they never did before.
Signet of the Locust and Quickening Thirst do not stack.
However, having a mainhand dagger and an offhand dagger stack to the same 25% speed increase as the signet. Thus, if you have quickening thirst and dual wield daggers, you don’t need the signet.
I tested this with a stopwatch.
No speed buffs stack speed.
