I suggest using 5 Crimson Archon Shards with Ability Strength or Melee Critical Damage (10% ability strength would also grant 10% melee critical damage on the line, whereas 25% melee critical damage would just be 25% melee critical damage. Yes, the ability strength would benefit Navigator and Eclipse, but those are also straight-up dependent on your Critical Damage. It's hard to calculate what's better. The flat ability strength might be better if just camping, but if moving around and using the [Glaive] without lines, the melee critical damage would of course be better. It also depends on your riven (if you have one on the [Glaive]). I suggest just using either one or a mix of both.
^Honestly I'm going for ability strength, but that's also because I enjoy Navigator. Going with ability strength also further buffs the line for your allies.

PLAYSTYLE:
1. Pick up an energy orb.
2. Shoot a Dashwire Arrow (1) to make a line you can sit on (Your critical damage will be buffed thanks to [Empowered Quiver], the amount can be seen on top).
3. Sit on the wire and throw the [Glaive] landing heavy attacks (hold down the melee button and press the heavy attack button (M3 on PC, R3 on PS) when it's near enemies.)
4. Profit.

With the right build, you can do MILLIONS of damage even WITHOUT NAVIGATOR AND ECLIPSE

And if that wasn't enough, you can multiply that with 11 if using Navigator and even more with Eclipse :O

MODS:
[Fleeting Expertise], no reason to max rank, since its only 0,01 and 0,02 energy drain difference (min and max) the duration is more benficial.
[Vigilante Pursuit] instead of Power Drift if doing Index.

ARCANES:
Molt Augmented or Arcane Fury
