You are definently ready (gearwise), your arena idea is fine, however, personally I prefer just using a Gravity Potion (if you already built a Skybridge just make a new world and fight him there). Cobalt Shield definently because you are not traveling in Liquids. Also try to upgrade your Hermes boots to Lightning Boots. This will help a lot (1 x Hermes and 1 x Rocket= 1 x Spectre then 1 x Spectre and 1 x Anklet of Wind and 1 x of Aglet= 1 x Lightning Boots). Might want more health potions as well.
