Fleeting Expertise

Fleeting Expertise increases Power Efficiency but reduces Power Duration of Warframe abilities.

Tips

 * Benefits powers that are not affected by duration the most. Thus, it is recommended to equip this mod on frames that are not heavily reliant on Power Duration such as Mag.
 * Maxing this on Nova will cause Null Star to only spawn 2 particles.
 * Saryn's Miasma ability deals a set amount of damage over its duration, so reducing its duration will increase the damage dealt per second while the ability is active.
 * Keep in mind, however, that this will severely lower the usefulness of the rest of Saryn's abilities.
 * A combination of  and  can almost completely negate the Power Duration penalty of this mod.
 * Also, if using a max rank, Power Duration is only affected by a very small amount of 5%, versus a 2% affect of Continuity and Constitution, but with the advantage of only costing one mod slot.
