After some testing here are my results: [u]DevourAsp timer cap tiers[/u] T0: 5s T1: 10s Echo of Starvation (orbs & breaches) provides 5s of time with Devour. Further pickups extend by 3s. Killing extends time by 5s. To get a [b]tier promotion[/b] you must break past the current cap by killing. You cannot be demoted unless you lose Devour entirely. Echo of Persistence increases the time gained by 50% rounded up, allowing access to a higher tier. You [b]cannot[/b] reach a tier that is over double the initial start time [b]before[/b] being rounded up. 5+50%=7.5s×2=15s TEoP: 15s [u]DevourSF timer cap tiers[/u] Tf: 11s These tiers are dependent on the circumstances when you initially gained Devour. I labeled the Devour buffs different to say they are not compatible. If you begin to Devour from an orb/void breach, you fall under the DevourAsp system. Equipping SF after this fact only provides a method to retain the current instance of Devour by setting your time to 11s regardless of current time. If you equip EoP [b]after you cast[/b] your rift with SF or Solipsism (on Prismatic) equipped, it will unlock the 'TEoP' tier (cannot be demoted). 15s is the maximum, [b]full stop[/b]. Again, this buff is instance based; to get a higher tier you must lose the Devour buff entirely. If you have EoP & SF both equipped and lack the Devour buff on rift cast, you bypass finite time and shape a new limit. Tpf: 11+50%(5.5)=16.5>1[error]s Max Limit (collapses into itself)=15+50%(7.5)=22.5>22 N×thing is past the 15s cap, full stop.
