As good as N6G4 sounds, it does have its trade-offs:
N6G4 Pros:
- 1.396x damage (N6 14000% vs G6 10000% bonus)
- 2.5x toughness (from N6 bonus)
N6G4 Cons:
- Requires Natalya’s Slayer equipped (loss of weapon slot)
- Requires Natalya’s Reflection equipped (loss of 1 ring slot)
- Requires RoRG equipped or in cube (loss of 1 ring slot)
- Requires Rain of Vengeance equipped and used (loss of 1 skill slot)
So in total, you gain about 40% damage and 60% damage reduction for two rings and a weapon. This disables the use of Focus and Restraint.
Instead of using N6G4, Elusive Ring provides the same 60% damage reduction for 1 ring slot (provided you use a skill like Smokescreen Vanishing Powder every few seconds). Next, Convention of Elements provides a time-averaged bonus of +50% damage by itself as another ring slot. Also, Focus and Restraint combine for 2.25x damage. Lastly, the weapon slot could be any number of options ranging from Odyssey’s End, Dawn, Fortress Ballista, and Echoing Fury.
TL; DR: I don’t see N6G4 as a very good build because of the large sacrifices needed for moderate benefits.
By using Hellcat Waistguard, you miss out on Hunter’s Wrath. And if you instead cube Hunter’s Wrath, you miss out on Depth Diggers. A huge loss either way.
