When starting the game you will want to chop atleast 100 wood and slay all slimes you can find. When you got your wood you should try to find the desert. Try going left first, if there is no desert to be found, then kill yourself and go right. When you're in the desert you will want to grab 100 Cactus. With 100 cactus you will be able to craft

1. Cactus Sword[terraria.gamepedia.com]
   
2. Cactus Pickaxe[terraria.gamepedia.com]
   
3. Full Cactus Armor[terraria.gamepedia.com].

Now that you've got some gear, you should go mine for some rescources. With your Cactus Sword you will easily be able to defend against mobs.

You're gonna want to search for a cave (Should have found one by now). When you're at the cave you should craft some torches from the wood and gel you've gotten on your recent journeys.
You will want to grab every ore you can find except
Tin and Copper.

There's really not much to say about this one.

King slime can be be summoned in two ways.

1. A player uses a slime crown. The slime crown can be crafted with a Gold / Platinum crown and 20 gel at a Demon/Crimson altar.
   
   
2. King slime can also be spawned by killing 150 slimes during a slime rain. The slime rain has a small chance of occuring when the player has atleast 140 Health and 8 Defence.

King slime is different from all other bosses in a way, normally bosses run away when you die. King slime dosent. What this means is that it dosent matter what gear you use. You will always be able to kill it. King slime has 2000 Health, AoE weapons is recommended for a quick kill.

EoC has a 33% chance to spawn in pre-hardmode when the player has atleast 200 health. It can also be spawned with a Suspicious looking eye. It can be crafted with 6 Lenses at a Demon/Crimson Altar (Lenses are dropped by demon eyes). EoC can only be spawned at night.

EoC has 2800 health in non expert-mode, after it loses 1400 health it will go into its second stage.

• Weapons: Basically all weapons that is ranged single target works for this boss, best option would be the snowball cannon. (Found in ice chests)
  
• Armors: Cactus Set[terraria.gamepedia.com]
  
• Health: 160+
  
  
  
  

EoW can be spawned by either destroying 3 Shadow orbs with a hammer or bombs. EoW can also be spawned by using Worm Food, wich can be crafted with 30 vile powder and 15 rotten chunks at a demon altar.

When killing a part of the body of EoW it will split, the boss can get really dangerous when its split multiple times. Thats why you always should focus the head.

• Weapons: Spike balls or grenades is the best option. Any AoE Weapon works decent against this boss.
  
• Armors: Cactus Set[terraria.gamepedia.com]
  
• Health: 200+
  
  

BoC can be spawned by either destroying 3 Crimson hearts with a hammer or bombs. BoC can also be spawned by using a Bloody Spine, wich can be crafted with 30 Vicious Powder and 15 Vertebrae at a crimson altar.

BoC will spawn with 20-30 Creepers. BoC Cant be damaged as long as the creeper are live. After killing the creepers the boss will go into its second stage and is now vunerable to damage.

• Weapons: Spike balls or grenades with a snowball cannon is the best option. Any AoE Weapon works decent against this boss.

The dungeon cant be entered untill skeletron has been defeated.
Skeletron is summoned by speaking to the Old Man at the Dungeon's entrance, at night, who will die and spawn Skeletron when you select the “Curse” option. If you speak to the Old Man during the day, he will ask you to return at night. You will only be able to summon Skeletron once per night, as the Old Man will not respawn until day.

The Wall of Flesh is summoned immediately when a Guide Voodoo Doll is destroyed by being dropped into lava in the Underworld while the Guide is alive, killing the Guide. Dropping the doll into lava outside of Underworld or when the Guide is not alive will not spawn it, and the Voodoo Doll will be destroyed with no effect. In the Desktop version Desktop version, the Wall of Flesh can also be summoned by killing the Guide in the Underworld using lava.

The Wall of Flesh's sweep direction is determined by its spawn location. Spawning it anywhere left of the center of the world will cause it to sweep from left to right, while spawning it right of center will cause it to sweep right to left (regardless of the direction the Doll was thrown). Maximum fight space can be achieved by spawning it at the extreme right or left of the world, though these areas have fewer natural structures and may require additional lava survival gear or construction. Be aware of the fact that The Wall of Flesh might not fight but just leave the battle if you spawn it too close to the edge.

(Do this boss first)

The Destroyer is a worm-like boss, much like the eater of worlds.

The Destroyer can spawn randomly on any given night once a demon or crimson altar has been smashed, as long as it has not yet been defeated in the current world. It can also be summoned manually using a Mechanical Worm at night. Night time is the only condition required for summoning (unlike Eater of Worlds, which requires a Corruption biome). Its arrival is announced by one of two messages: "You feel a quaking from deep underground..." or "You feel vibrations from deep below...." It must be killed before dawn, otherwise it will despawn. If this message pops up and you log out, it will not spawn.

The Twins are a Hardmode Mechanical Boss which is essentially a harder version of the Eye of Cthulhu. The Twins are two separate flying entities connected by a tendril, each with its own attack pattern and life count. Both must be killed in order to defeat the boss.

The Twins are summoned using the Mechanical Eye at night, and must be defeated before dawn, otherwise they despawn. If an Altar has been destroyed, they also have a chance of spawning on a random night if they have not been defeated yet. Their approach is signaled at dusk via the chat message, "This is going to be a terrible night..."

Skeletron Prime is a Hardmode Mechanical Boss which is essentially a harder version of Skeletron. It is summoned with the Mechanical Skull at night. Players have until dawn to defeat it.

The golem is a rather easy boss, and you can fight him with the same gear as you used for plantera. The ''hard'' part about golem is getting to the boss room because of all the traps. Try to not touch the floor at all since its filled with pressure plates. Use your wings / hook to get around the room without touching the pressure plates.


Golem is summoned by clicking on the Lihzahrd Altar, located in the final Jungle Temple chamber, while at least one Lihzahrd Power Cell is in the player's inventory. One Lihzahrd Power Cell is contained within each of the Jungle Temple's Lihzahrd Chests,
and can be dropped rarely by Lihzahrd enemies. Golem spawns directly above the Altar.

Moon Lord is a Hardmode, post-Lunatic Cultist boss. It is Terraria's final boss. It appears at the conclusion of the Lunar Events, once the final Celestial Tower is defeated. It can also be summoned manually using a Celestial Sigil.

If all players die during the battle, the Moon Lord despawns. It can be re-summoned by completing the Lunar Events again (the Cultists required to initiate the events re-appear at the Dungeon's entrance), or by using a Celestial Sigil.

   A good stratergy is to build a house with plattforms as walls, a bed and the nurse living inside.
   The bed will allow you to set your spawnpoint there so you can use your
   Magic Mirror[terraria.gamepedia.com]. This allows you to constantly go back to your nurse to heal when you're low.
