Efficient Transferral lengthens the duration of an Archwing's abilities by 7.5% per rank, with +30% at max rank at rank 3. It helps Archwing powers stay active for longer stretches in aerial missions.
It drops randomly from Pursuit missions on Pandora, Saturn, and there is no vendor for it. Use it on Archwings with timed buffs or crowd-control powers, where a longer duration matters more than raw efficiency.
Efficient Transferral was added with Update 15.0 (October 2014).
Efficient Transferral is tradable, see the current prices in the market box above.
