Terraria Tools

How the lookups chain together

The first three tools are three views of one wiki dump, and they are deliberately wired to hand off to each other. You almost never start with the question you actually want answered — you start with the thing that just killed you, or the sword somebody mentioned.

1. Search the creature in the Bestiary. You get its Classic-mode health, damage and defense, where it spawns, which debuffs it ignores, and every item it drops with the chance attached.
2. Click a drop. That opens Item Source on that item, which is the same question turned round: everything else that drops it, which chests and Treasure Bags hold it, and whether it can be crafted or bought instead of farmed.
3. If the item is craftable, Item Source shows a Crafted badge that opens the Crafting Tree on it — the recipe, the station, and every ingredient expanded down to the ore.

Item Stats sits beside that chain rather than in it. It answers the question the drop table cannot: whether the thing is worth the farm. Base damage, damage type, crit, knockback, use speed and tool power, so you can put two weapons next to each other before you commit an evening to one of them.

Which version of the game this tracks

Four of these pages are generated rather than written. The Bestiary, Item Source, Item Stats and Crafting Tree were built from the tables on the official wiki, terraria.wiki.gg, in a single pull on 18 July 2026 — that snapshot covers 531 creatures, 6,097 items, 1,005 weapons, tools and armor pieces, and 3,905 recipes. The wiki documents the PC release, so these are PC numbers; console and mobile builds lag behind and can differ.

The NPC Happiness Calculator is the one page pinned to a named version, and it says so out loud: it implements the 1.4.4 "Labor of Love" happiness system — loved biome or neighbour ×0.88, liked ×0.94, disliked ×1.06, hated ×1.12, a solitude bonus, a crowding penalty, and a final price clamped between 75% and 150%. It also keeps the 1.4.4 pylon rule, where a vendor only sells their biome's pylon at 90% prices or lower. 1.4.5 later dropped that threshold, and the page deliberately does not model it.

Two more limits worth knowing before you trust a number. Bestiary stats are Classic mode — Expert is roughly double the health and damage, Master roughly triple. Item Stats are base stats, before armor, accessories, buffs and reforges, which is exactly why they are comparable between two weapons.

Why happiness shows up in your reforge bill

Reforging is a slot machine: the Goblin Tinkerer gives a random modifier and you re-roll until you hit the one you want, so the real limit is not luck, it is coins. Each roll costs roughly a third of the item's value — and that price runs through the same happiness modifier as everything else he sells.

Which makes the happiness calculator a reforging tool. He likes the Snow biome and gets on with the Mechanic; put the two of them there together and his multiplier drops toward the 75% floor, so every re-roll on the way to Legendary or Unreal costs a quarter less. The same modifier moves the Nurse's healing fee and what every vendor pays you for loot.

Decide the target modifier first in the Reforge Guide — Legendary for melee and whips, Unreal for ranged, Mythical for magic, and a pure-damage roll like Ruthless for minions, which ignore crit, speed and knockback entirely.
