「Brown Dust」World Boss: Arcstar 5.8m Point [29/04/19]

My formation on World Boss Arcstar using Eldora as main DPS.

Tips & Detail below.

Unlike Ogdoad, Arcstar is not immune to Stats Weakening skills type so we can make a good use of those skills.

First you must stacking curse 'til the boss Defense and AGI is 0%.
And then stacking Incoming DMG Boost skills as much as possible.

And that is the reason why Zarka and Orienne is a must have here (+10 if possible)

Also you may wonder why Eldora works so great on this boss. It's because of her second skill Descending Sun. The additional damage done by this skill is ignored damage reduction effect, Which our Arcstar has 150% damage reduction on his DoT Immunity.

So other mercs with this kind of additional damage such as Mamonir, Karin and Valze also working as good as Eldora does.
