How to defeat plantera in terraria mobile
There are many tips to kill Plantera. Here are some of them:
Wide Space
Make a wide space for you to travel. That will make Plantera not hit you that much and you can dodge him. Try going in a clockwise direction to make him go in circles.
Artificial Jungle
You can make an artificial jungle with mud and jungle grass seeds. Plantera's Bulb may spawn in your artificial jungle.
Bows
If you use a bow, you can use Chlorophyte Arrows. They bounce off walls, and that helps to hit Plantera a few times per arrow.
Shield
A Cobalt Shield is also useful as you will not be knocked back by Plantera.
Armour
Cholrophyte Armour is fine. Beetle Armour too.
Last But Not Least
A Flamethrower would be nice. It shoots a continuous stream of flame, which helps to attack Plantera. It can be easily crafted after defeating Skeleton Prime.
Turtle armor, Clockwork Assault Rifle or Megashark with explosive bullets, if you could get 2 more broken hero swords, terra blade,and a optic staff, and a big arena with no background walls so it cant grapple on to anthing. Also for accessories, have a nice pair of wings, a emblem for whatever class you are, and then whichever other accessory you fell like you need.
