Ah, sure thing.
>Arena is just two rows of solid blocks with a long platform in-between, about 50 blocks off the ground as the other anon said
>The solid blocks are there to hold random buff items, but also to make the Destroyer's movement more predictable
>The platforms are to get easy damage with Stormbow and the Nimbus Rod
>Dart Pistol with Crystal Darts for crowd control against the probes
>Sanguine Staff/Blade Staff, again for crowd control but also supplementary damage
>Nimbus Rod for bonus extra damage against everything
>Daedalus Stormbow because it just melts the Destroyer
>For buff items I used fireplaces, heart lanterns and a few Bast statues I had lying around. Also a gnome, for good luck.
>Frost Armor as a good all-rounder for ranger builds
Accessories are:
>Ranger Emblem
>Terraspark Boots
>Magiluminecense
>Frozen Wings (got them while farming for Frost Cores)
>Ahnk Shield for knockback resist

I also buffed the shit out of myself with every potion that was easily available, including some soup for the 2nd tier of the well fed buff. If you guys haven't really tapped into potionmaking, you really should.
