I don't know if there's any other glaive-enthusiasts here but for a while I've been trying to find a build that actually works well with a glaive. My previous setup was to use Vesper of Radius with a glaive and become a literal brick wall (the glaive shield gives something stupid like a 95% damage resist) but you could kinda do that without Vesper...
cont.
I might've finally found a (borderline broken) build that semi-relies on a glaive - think portable healing, unlimited armor charge, jolting anything that touches you... I just need to do a bit more build/theorycrafting to perfect it but the general gist is to whack everything with ACD Feedback Fences equipped - each melee _hit_ gives 1 armor charge. To my surprise, this actually works with the glaive melee...
Loaded into Terminal Overload without any friends and yeah... surrounded (enhanced) one shots the red bars here
And yeah, survivability doesn't really seem to be an issue - rip that poor goblin that whacked me
