Secant Filaments granting Devour overrides current Devour buff. Using Echo of Persistence to prolong how long Devour lasts and Secant Filaments to initially grant Devour, when using an Empowering Rift again, the timer gets reset back to 10 seconds instead of not resetting the time since I had more than 10 seconds on the Devour buff. Example: I had been at ~20 seconds on my Devour buff after defeating some enemies, using Echo of Persistence to prolong the buff. I place another Empowering Rift thinking that since my buff is over 10 seconds, nothing will happen and I will keep current time. Instead, the buff is reset to 10 seconds.
