1 bring lots of snow blocks and pumpkinss and a shovel. make snowbos. they make snow which can destroy the things that give the dragon health
2 DONT DO IT ALONE
3 wear no armor. chances are you will lose it
4 bring a bow, arrows. sword, tnt and flint and steel, if you can time it right tnt can hurt the dragon a lot
