Re-Logic 2D Sandbox Adventure · Action Adventure / 2D Sandbox
1.4.5 data: 11 pylons and happiness pricing, housing checks, DPS/TTK and reforge odds, and combo strings for all 37 secret seeds. For server owners: version-split guidance, serverconfig (with all 15 Journey permissions), TShock 6 and Linux deploy artifacts.
1.4.5 rules: happiness only moves prices, it no longer gates pylons. Includes 10 registered disputes and the legacy neighbour chart
Checks all 10 housing rules (1.4.5 lets the home tile be a platform) plus activation and troubleshooting for all 11 pylons
Official-formula net damage, crit and attack speed with 18 boss presets, plus incoming damage and the 1.4.5 whip tag changes
Reforging has no memory: independent rolls, flat cost. Includes the official pool sizes (14/19/24/36/40) and a cumulative probability curve
Only decision-critical chains, centred on the new 1.4.5 Aether pylon route; the full 312-entry dump lives on terraria.tools
The rebuilt 1.4.5 seed system: all 37 are new and freely combinable, with one-click all-on and True Zenith string generation
18 bosses in the recommended order with defense and baseline HP; tick off kills and see the next target
Weapons, accessories and the per-stage 1.4.5 changes; the summoner column follows the rewritten rules
12 common potion recipes plus a fishing-power calculator (rod + bait + gear × time / weather / moon)
Milestones across NPCs, pylons, bosses, stations and quality of life — 8 of them changed thresholds or gained mechanics in 1.4.5
The biggest 2026 server-owner trap: vanilla 1.4.5.7 / TShock 6.1.0 (1.4.5.6) / tModLoader on 1.4.4 — the three are incompatible
Generates the 8 fields hosting panels usually hide, including all 15 Journey permissions; annotated mode available
36 common commands plus 8 REST endpoints, including 6.x additions (.NET 9, PostgreSQL, whitelist IP ranges)
SteamCMD install + serverconfig + systemd unit (with TERM=xterm) + scheduled backups + screen fallback, generated in one go
21 built-in console commands, 18 launch flags and a network/path cheat sheet, each checked against the official wiki
Four hardware tiers, the npcstream trade-off and nine preflight checks (TERM, ports, multi-instance, auto-save …)
| Port | Protocol | Purpose |
|---|---|---|

| 7878 | TCP | TShock REST API (off by default; if enabled, change the token and bind to localhost only) |

serverconfig.txt~/.local/share/Terraria/Worlds/<世界名>.wldbanlist.txttshock/config.jsonThe dedicated server is app id 105600 and SteamCMD pulls it anonymously — Terraria is one of the few games whose server costs nothing extra. One TCP port, 7777, carries both game traffic and the Steam server-list query; the official wiki suggests cloud hosts (AWS/GCP) open TCP and UDP both. Everything lives in serverconfig.txt, launched with ./TerrariaServer.bin.x86_64 -config serverconfig.txt. Lines starting with # are comments, so your change must go on a new line — the classic "I changed it and nothing happened" moment. autocreate only fires when the .wld named by world does not exist yet: 1 small, 2 medium, 3 large. Worlds default to ~/.local/share/Terraria/Worlds/. On Linux the server refuses to start when $TERM is not xterm and reports "Magic number is wrong: 542" — export TERM=xterm fixes it. Run several instances and you must change three things together: config file, worlds folder and port. The biggest trap in 2026 is the version split: vanilla 1.4.5.7 / TShock 6.1.0 (on 1.4.5.6) / tModLoader still on 1.4.4, and the three are mutually incompatible — mods mean everyone stays on 1.4.4. Since 1.4.5.0 the world auto-saves when the last player leaves; since 1.4.5.7 empty servers stop ticking. On performance, the server is effectively single-threaded, so extra cores do not help and the bottleneck is always single-core clock rather than RAM; npcstream (the sync radius) is the one knob that actually changes how it feels.
