Aetherflow (ARC)

[RaphaelDDL]

At lvl 30 you get Bane. An ability that allows you to make your DOTs to spread in a zone. And each use costs one Aetherflow.
And having it on increases your mana pool and you can recast it fast if you are using drain for spike damage

The first time I had to actually use Aetherflow due to mana running out on my ACN was versus Ifrit, when I helped tank with Topaz (thus having to heal nonstop).
Other than that, I never use it also. But good to know I'll have to on lv30.
