Vincent + Akasha combo (No bomber specs)
Hermes + Lantern (Supported with Akasha for max efficiency)
This is why you have to work on trascendence and getting your hunters to the Master Hunter (5 stars class). Even with minimal trascendence, the effects on your hunter's power will be considerable (T3 makes them perform their best, clearing abyss stage 5 even on less than 30 seconds). :).
T3= Trascendence degree III
5* = Master Hunter class (highest level released for a Blustone's Hunter).
There's also some Arena memes.
