So, I'm guessing you are at the beginning of the game since you said "copper armor". This boss is super easy. You don't need a lot of platforms, just enough to make 3 or 4 rows. Next, find the corruption and find shadow orbs. In order to do that, bring tons of bombs with you. Destroy a shadow orb in order to get a Musket. Then, the Arms Dealer will appear. Save up 5 gold to get the Flintlock pistol and some silver for more bullets. This boss will be easy. Don't fight the Eater of Worlds before the boss, for EoW has more health that EoC. Try to fight the Goblin Army before EoW, too. The Harpoon the Goblin Army drops will be enough to kill the EoW. PS: You can definately beat the EoC if you follow these steps. Hope this helps!
