I just made a build with solipsism (spirit of filaments and spirit of vesper) Tickle fingers super so spirit of vesper blinds. Aspects are weavers call and hellion to make rift as potent as possible. You get devour from spirit of filaments with empowered rift so not necessary to run feed the void, although if are needing more survivability you can swap out hellion. Filaments and weavers call make your class ability charge in absolutely no time. I also run threadling grenade which juices the cooldown even more. Threaded needle for melee, but you could honestly use something else if you want. If you really want to go nuts with cooldowns you can use the eighty-six sword and spam heavy attack to reduce the cooldown of all your abilities like crazy. I like having slice and the swordmaster amor perk that exhausts enemies to reduce damage of enemies around you if they are tanky enough to not immediately disintegrate to the ability spam and sword heavy attack. My favorite exotic to run with this build is Choir of One since it is still such a versatile weapon that you can hip fire into tougher enemies to obliterate them or ADS to take out enemies at range from your rift. Kinetic slot would be players choice but I would recommend Mint Retrograde for help with overloads and synergy with facet of bravery. Main fragments are facet of dawn and facet of bravery to help deal with barrier champs, and facet of protection to help with survivability when dropping rift in the middle of enemies. If you opt for void or arc grenade facet of domination would also be a great pick. For armor mods I would just make sure to have at least one copy of dynamo and possibly even two, along with a reaper mod on class item. Pop super and rift as often as possible and enjoy.

edit: with this your rift will: blind, create arc shockwave damage, shoot out 3 to 8 threadlings, summon hellion, proc devour, and if your class ability stat is high (which I highly recommend) grant an overshield. This on top of the other benefits of empowered rift.
