He said perma invis, which means with only e-siphon being able stay invisible forever without picking up energy, and without fleeting it will cost 27.5 energy(that's with essence) and over the 30.8 sec with all duration mods maxed you will only regen 18.5 energy, so you need fleeting for perma invis, unless you are playing with someone else with e-siphon.
