The Fight

Start shooting Calamitas and fly to right side of map, when you´re in sticky situtation, use recall potion and wait for Calamitas when you see lasers start shooting at right and fly to left. Repeat this until, Calamitas summons Cataclysm, but focus still on Calamitas. Do the same with Catastrophe. When he says “Most Impressive Child, Most Impressive”, Start using Recall Potions more commonly. When Cataclysm and Catastrophe awokens, start focusing on Catatrophe, then focus on Calamitas again. Do this until Calamitas dies.

Note: You should kill Plantera before Calamitas, because Plantera is way much easier!
