This build utilizes heavy attacks to quickly take down enemies. This build—aside from the arcane—can also be replicated onto any scythe or any other weapon with strong heavy attacks (scythes, claws, machetes, etc) and decent crit stats; however, some alterations may be needed (life steal, status mods, etc). One swing can efficiently and consistently kill enemies up to level 200 or so.
While it says this build is 5 Forma, there are 4 Forma (Vx4) I have added to this build. The additional polarity comes from gilding the zaw, in which you are able to add one polarity (V in this case) of your choosing.
In order to effectively use this build, you should spam heavy attacks constantly. Kills will proc Exodia Brave in order to regain energy far quicker than Zenurik's Energizing Dash. I use Vazarin because of this, and I use Protective Dash instead of Life Strike for healing. You could use Life Strike in place of [Spring-Loaded Blade] if you are willing to lose 2m of range (SLB procs on every heavy attack since each attack procs slash).
I have been using this melee a lot recently. It is more reliable and offers more to the table than [Redeemer Prime]; it provides energy (and possibly health) restoration and is able to kill multiple enemies in one attack. Redeemer is more of a single-target weapon, and is more efficient in doing so (using this melee on beefy enemies requires waiting for the slash proc to kill them). but is by no means named useless because of this melee weapon. I prefer this zaw due to the wide swings and energy/health restoration capabilities.
