Terraria Update!

I have been playing Terraria for a while now. I am not on Hardmode but everyone has a so kind and donated to me(I have also been sneaky and stole a ton of items from peoples chests). I have demon wings and shroomite armor which are totally amazing.  I actually have a 'The Horseman's Blade' which is the second best sword. I still need help though. I am going to vs all the bosses. I have already beaten the Eye of Cthulu and Skeletron. If you have any tips for the other bosses, please tell me in the comments.
