Monkey tail, shadow wings, booster hat and if you need to cross river, wear flipper hat. Bring something that will make you move faster, if the retreat option is necessary.Make sure the intervals between food consumption are reasonable, otherwise you will get the Shame! hat.Make sure you have lots of Food, because a base is meant to be defended easily, and they will harm you.They will have to mine down the walls to get out, or kill themselves. If there is only one entrance into the base, put a stone mine in front of their entrance and exit if that if there way in and out.Bring your team if you have one: more people, more power.Just make sure you have something to block the turrets from shooting at you.Use Samurai Armor to mine down on their defenses faster.Shoot through their walls, since Arrows can go over walls.Wear an Emp Helmet to stop turrets hitting you, and use a Great Hammer to break traps and walls.If you are trying to invade someone's else base, or just annoy them, or for revenge, try this: Putting yourself in a place you cannot retreat from is a one way ticket to death. Ideally add a back-up Teleporter, or make a way that is easy to retreat (e.g.: in the river with Flipper Hat equipped, or the Snow Biome with a Winter Cap. Finally, it is always a good option to have a retreat.Just don't go over the normal limits: 2 turrets, 30 walls, 1 spawn pad, 7 windmills, and so on If you are designing a base, use sandbox.
A good way is put your base at the corner of the map, or at the edge of a map near a river, and make one way in.A base needs to be easily defended and needs to be able to have an entrance and exit (it could be just one way).You can then level up again and acquire stronger weapons.(not needed in sandbox) After you make it, put own a spawn pad, die on purpose, and you spawn in your bases.
