Terraria 1.4.5.8 client • released 04 Oct 2026 • 30.3 MB

Already have IsaClient? You don't need to download anything: it updates itself when you open it.

What's new

World Edit: the complete World Edit from ZazaMod (selections, fills, biome conversions, brushes, schematics, image drawing and undo)
Schematic paste fixed: doors, banners, Living Wood, furniture and other multi-tile objects are pasted correctly, large pastes no longer crash on TShock, and paste speed follows your packet rates
Music player: Now Playing, queue, library, favorites, playlists and a floating mini player; plays links from YouTube, SoundCloud, Spotify, Apple Music and Deezer, with autoplay, background playback and hotkeys
Multiclient & bots: join up to 30 bots to your server that follow you, fight or chat with AFK AI, and play as any of your sessions or switch servers without reconnecting
Proxies: a personal SOCKS5 proxy for your own connection (.proxy), managed from the main menu

Open your Terraria 1.4.5.8 folder and keep a copy of the original Terraria.exe.
Put the downloaded Terraria.exe in its place.
Start the game. From now on IsaClient updates itself.
