From personal experience the best arenas for fighting the Twins is a sky bridge, a really long sky bridge. Running from end to end and ad looping over/under them to switch directions.

Now this assuming you havn't beaten them

There are 2 main loadouts in my opinion, Ranged and Magic.

For Ranged use a high tier Ranger armour like Titanium or Adamantite with either a strong bow/crossbow or a tactical shotgun/clockwork assult rifle/megashark with crystal, ichor or explosive bullets. along with standard ranger accessories (ranger emblem reforged to menacing or warding depending on your prefernce.

I don't recommend using magic as the high DPS magic weapons really are not availiable to you before the mechanical bosses and Spcetre armor is a must have for any magic boss fights which isnt avaliable until after beating Plantera
