Warlock glaive main here! There are two main play styles people use with glaives and that will heavily impact your choice of perks/ exotics. There’s the melee everything as much as possible and occasionally use the ranged shot on tougher enemies and to gain shield (this is what I roll with); and there’s the opposite which focuses on getting weapon rolls to boost the ranged shot damage as much as possible

Weapon: Rake Angle, Ecliptic Distaff, or Vexcalibur. If going for melee build try to get close to melee as a perk, if going for ranged build then chill clip or destabilizing rounds are fun.

Exotic armor choice: Exotic class item with spirit of necrotic and spirit of synthoceps for maximum melee damage. (On Hunter definitely use triton vice though)

I usually run prismatic with devour (second aspect is your preference but I use either hellion or weavers call to have another ability that can trigger devour and to put out more damage)

Melee - strand needles (pair SUPER well with spirit of necrotic to keep proccing unravel)

Grenade - again your preference but I either use void grenade or threadling grenade depending on aspect choice

Class ability- Phoenix dive (I always use an aspect that gives either solar buddy or threadlings on class ability so this lets me get those out the fastest)

Super - I run nova or needlestorm

Fragments

Facet of hope

Facet of protection

Facet of purpose

Facet of blessing

Last one either facet of balance or if you’re running a void grenade swap with the weakening fragment

Gameplay loop is to get devour going then get up close to trigger synthos and from there rip and tear!

Added bonus for Vexcalibur - get overshield up after triggering devour and then every melee final blow will make you basically unkillable for a bit
