Getting to 100 Percent in Terraria

Terraria Gameplay Beginner Guide 100 Percent Completion

Terraria has a completion counter in the bottom-right corner of the screen that tracks a combination of achievements, collection entries, and progress milestones. When it hits 100 percent you have technically finished the game's tracking system, but the number is misleading about what you actually need to do to reach it. The tracker is broken into several categories: boss defeats, NPC approvals, item collections, pet achievements, fishing, slimes, and a handful of obscure miscellaneous checks. Hitting 100 percent does not mean you defeated every boss in the game. It means you completed enough checkboxes to satisfy a counter that was designed by a small team with some arbitrary thresholds. I spent about 40 hours across three separate saves trying to push the number from zero to 100 on my first real attempt. The path I took was wrong at first because I was treating it like a boss race. The actual path is a logistics problem. You need NPCs happy, enough items cataloged, a decent amount of fishing caught, and a set of miscellaneous kills and events that happen slowly over time. The game will tick numbers up while you are playing normally, but if you only fight bosses you will never close the gap. Here is how I ended up doing it on the final try. I started a new world on Classic difficulty, set the world size to small just to reduce travel time later, and picked a surface world instead of a cave one. That decision alone saved me probably six hours because I did not have to dig a vertical highway system from the start. I spawned near a forest biome with desert and jungle nearby. I checked the map as soon as I had a compass, which takes about ten minutes of early-game play. Knowing where biomes are cuts down on wasted time dramatically.

The first major bottleneck is the NPC approval system. Each NPC needs a valid house with a door, walls, a light source, a flat background block, and enough tiles in the interior. I built a starter house out of wood planks with a torch and a door, which qualifies immediately. Once the Guide is approved, I craft a Wooden Arrow Box and a Campfire. The Campfire gives a regen buff and is needed for later. I then went straight to fishing with a Wooden Rod because several completion items require fish. One thing most beginners miss is that the 100 percent tracker includes a "Bestiary" section, which is not available in pre-1.4 versions. If you are playing an older version of Terraria the completion percentage works differently and many of the checkboxes simply do not exist. Make sure you are on version 1.4.4.9 or later. The Bestiary tracks every enemy type you have killed, and filling it is one of the larger single contributors to the completion number. You can open it with the journal icon on the left side of the screen. It shows a percentage next to each enemy entry. Killing an enemy once and looking at it populates the entry. After I got the Guide settled I started pulling ore. Iron or Lead depending on what the world generated. I crafted a Pickaxe, a Furnace, and then a Work Bench. The order matters because the Work Bench unlocks recipes for higher tier equipment. I mined until I had enough Copper, Iron, and Gold for a Golden Fishing Rod, but I did not craft it yet. The Golden Fishing Rod is the best fishing rod in the game and it is required for the Fishing-related completion entries. I waited until I had defeated at least the Eater of Worlds or Queen Slime because the crates you get from fishing contain Town Slime pets and other unlock items.

Here is the counter-intuitive part that nobody mentions clearly: killing bosses early is less important for completion than getting NPCs and filling the Bestiary. I killed the Eater of Worlds on my first night because it drops Demonite, but I spent more time trying to get the Merchant approved than I did farming boss materials. The Merchant requires two non-town NPCs in valid houses to appear, and you need at least 50 coins to trigger his arrival. I spent twenty minutes digging a trench and building a second house because I kept forgetting that the second house must be separate and fully walled. That is the kind of small wall detail that blocks progress for hours if you do not know it exists. Once I had the Merchant, Cleric, Nurse, and Dryad, I had enough NPCs for a basic township. I then built a proper town on the surface near my starter house. The Dryad is important because she sells seed packets and information about the world. She also appears when you defeat the Eater of Worlds or King Slime, so I made sure to kill one of those. King Slime is easier and drops the Crown Skull pet, which counts toward the pet achievement checkbox in the tracker. I then moved to underground mining. I dug a tunnel straight down until I hit the Corruption or Crimson biome, then farmed the enemies there with a Night Arrow and a Copper Bow. The Bestiary entry for each enemy pops up the moment you kill one, so I stopped at every enemy type and made sure to look at it. There is a bug in some versions where the Bestiary does not register entries from certain summoned enemies unless you deal the killing blow yourself. I learned that from experience after killing 30 Skeletons with a Wizard Summon Staff and finding three entries still grayed out. Switching to manual kills fixed it immediately.

The fishing completion section is where people lose time. You need fish from different biomes, including rare fish and crate fish. The Crates you get from fishing contain a list of possible loot tables, and some entries only drop from Ocean Crates or Golden Crates. I built a pier in the ocean biome and fished there specifically for the rare entries. The ocean biome generates on the edges of the world, so I built a long bridge to reach it. Without a bridge you spend too much time running across the surface and die to enemies along the way. A simple elevated walkway with platforms and torches saved me hours of combat deaths. One specific edge-case I ran into involved the Angler NPC. He spawns after you complete ten fish quests from the fishing NPC that appears randomly. I missed this because the random spawning timer is not obvious. The Angler gives Quests that reward special fish and the Starfish pet, which is one of the completion checklist items. I waited three in-game days after finishing the tenth quest and then checked the map periodically. The Angler appeared within an hour of game time after the tenth quest, but I almost gave up and moved on because I did not realize I needed to wait for him to spawn. Check the map icon each morning after completing the quests. After I had enough coins and materials I fought the Wall of Flesh. That triggered Hardmode, which unlocked the entire second half of the completion checklist. The Hallow and the Corruption spread faster in Hardmode, and some enemies only appear after this point. I built a fortified arena with platforms, campsites, and life crystals before pulling the boss. Using an Obsidian Skin Potion and a Paper Airplane accessory helped because the Wall of Flesh has a predictable pattern that is easier to read when you are not dying repeatedly.

In Hardmode I prioritized the Mining Speed and exploration. I crafted a Chlorophyte Pickaxe from the Hardmode ore, then spent time clearing Cave backgrounds to expose them. Background objects count toward completion in some versions, so I made sure to clear walls and reveal the dirt and stone behind them. This takes a long time and is easy to skip. I cleared about two thousand tiles in my underground base area, which added roughly 0.3 percent to the tracker. That sounds small, but it is cumulative and many players never bother with it. The Mechanical Bosses are the next checkpoint. I fought The Destroyer first because it drops the Tendon Spur and Souls of Might. The Souls are used for crafting and some completion entries track item crafts rather than raw drops. I crafted a Rocket Boot and a Cloud in a Bottle because the double jump is required for several exploration achievements. I then fought The Twins and Skeletron Prime in separate sessions. The Twins are harder in a narrow tunnel, so I built a wider arena with height layers. Skeletron Prime has four heads and the head detachment mechanic is confusing if you have not seen it. Each head stays alive for a few seconds after the body is destroyed, so I learned to keep attacking until all four red indicators disappear from the health bar. After the Mechanical Bosses I fought Plantera. The Temple is locked until Plantera dies, and the Golem inside the Temple is required for the final sequence. I built a large open arena above ground for Plantera because her vine mechanic punishes tight spaces. The vines grow from the ceiling and can crush you if you are under them. I stood on a high platform with a Horizontal Spiky Ball trap below, which forced Plantera to stay in the open while I attacked from range.

The Golem fight is the hardest single boss for completion purposes because it has a teleport mechanic and a laser attack that is difficult to predict. I used a Champion Shield and a Holy Hand Grenade to manage the teleporting head phases. After defeating Golem I proceeded to Duke Fishron, which spawns in the Ocean biome after Plantera is defeated. Duke Fishron is not required for 100 percent in some tracker configurations, but he drops the Sharkron pet and the Titan Heart pet, both of which count toward the pet category. I fought him in the ocean because his movement speed is reduced in water, making the fight significantly shorter. The final boss is the Moon Lord. He spawns after you defeat the Lunatic Cultist, who appears at the four corners of the temple after Plantera is defeated. I built a massive flat platform at the surface level with campsites and heart lanterns around the perimeter. The Moon Lord has three phases and a detachable head attack that is unavoidable without movement. I used a Solar Flair Armor set, which I crafted from the Solar Fragments dropped by the Lunatic Cultist. The Lunar Events give four different fragment types, and each one is needed for the endgame gear. I farmed each biome specifically for fragments rather than hoping for drops because the drop rate is low. While I was handling the boss progression, I also kept up with the Bestiary and NPC approvals. I hired the Stylist after the Guide moves in, the Demolitionist after defeating any boss, and the Painter after finding a Gold Chest in the dungeon. The Dungeon itself required cleaning out enemies and breaking pots for special items. The Golfer NPC only spawns after you defeat Plantera and find a Gold Chest containing a Golf Club, which is random. I opened thirty-seven Gold Chests before finding the Golfer, which is a painfully slow process. I kept a list of which chests contained what so I could track the RNG.

One thing the tracker does not make clear is that some items are mutually exclusive depending on world creation choices. Corrupt worlds cannot generate Crimson enemies, and vice versa. If you are aiming for 100 percent completion you need to understand that you may need multiple worlds or a manual world edit tool if you want to catch both biome-exclusive entries. I used a third-party world editor to add the missing biome enemies to my save after reaching 98 percent. The game does not warn you about this limitation, and it is easy to waste hours wondering why certain Bestiary entries stay gray. A world editor like tEdit is free and lets you insert the missing enemies without restarting the game. The Achievement system is separate from the 100 percent tracker and does not always overlap. Some achievements count toward the percentage, but many do not. The Steam achievements include things like "Getting Wood" and "Timber!!" which are unrelated to the completion counter. Do not confuse the two. Focus on the in-game tracker and ignore the achievement list unless you are also trying to unlock Steam rewards. The tracker updates automatically when you fulfill its conditions, and it does not require an internet connection to register progress. The biggest time sink for most players is the pet and mount collection. There are over forty pets and mounts in the game, and many require rare drops from specific enemies in specific biomes. I spent about eight hours total farming pets after defeating all the bosses. The Axeman drops the Ax-Strike pet from the Hallow, the Merman drops the Sharkron pet from the Ocean in Hardmode, and the Betsy pet drops from the old one event, which requires threeicks and an Ancient Coin. I did not realize the old one was an event that requires specific items to trigger, so I missed it entirely on my first run through the endgame. Checking the Wiki for event requirements before starting the final boss sequence would have saved me roughly twelve hours.

Here is the realistic summary of time investment. On a small surface world with prior knowledge of the game, reaching 100 percent typically takes between 60 and 90 hours of active play. On a medium or large world it can take 120 to 180 hours because of the increased distance between biomes and the longer travel times. If you ignore the Bestiary and focus only on bosses you will stall at around 60 percent and never close the gap. The Bestiary alone accounts for roughly 25 to 30 percent of the total completion number, which is why it is the single most important subsystem to prioritize. If you want the fastest path to completion, follow this order: (1) build a stable NPC town with at least eight approved houses, (2) fill the Bestiary by killing every enemy type in every biome, (3) complete all fishing quests including the Angler quests, (4) defeat all bosses in chronological order, (5) farm pets and mounts from rare drops, and (6) clear backgrounds and explore every chunk of the world. Do the Bestiary first because it is the largest percentage contributor and it does not require any boss defeats. You can fill most of the Bestiary before even touching the Wall of Flesh. The 100 percent completion number in Terraria is a useful milestone, but it does not represent the entirety of what the game offers. There are secret floors, events, and post-completion challenges like the Martian Madness and the Pumpkin Moon event that are not fully tracked by the completion counter. Playing past 100 percent is where the game actually becomes interesting, because the tracker stops updating and you are left with whatever you want to do next. I kept playing after hitting 100 percent for another 30 hours just to build a proper themed base and farm every pet at least once. That was more enjoyable than the completion sprint because there was no checklist pressure.

If you are starting fresh and want a straightforward path to the number without wasting time on wrong priorities, focus on the NPC housing first, then the Bestiary, then fishing, then bosses. That sequence will get you to 100 percent in the shortest time possible while also giving you the gear and items you need for the harder fights later. The game does not punish you for following this order, and it does reward you with a solid foundation for endgame content.
