How do skill-recharge enhancing effects stack?
For example, suppose I have Quickening Zephyr (all skills recharge twice as fast) and Mantra of Inscriptions (signets recharge 40% faster) on me and I am using a signet that takes 10 seconds to recharge normally. Does it interpret the "twice as fast" as "-50% to recharge time", add that to the -40% from MoI, and then it's -90%, so the signet recharges in one second? Or does it take the 40% off to get to 6 seconds, then halve it so it's 3 seconds? Or something else entirely?
