How big would a good Plantera arena be because I can't defeat Plantera and my defence is 62 and I had a ruthless mega shark with crystal bullets and my friend had a rainbow rod with clairvoyance active, we made it to phase 2 and then died I tried the arena but it didn't work, was it because it was to small or I didn't put enough platforms in? Because I really want to beat him because I want vampire knives and the cyborg so bad!
