IsaClient v1.3.9

Terraria 1.4.5.8 client • released 11 Oct 2026 • 30.6 MB

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

What's new

This is the last IsaClient based on ZazaMod. From 1.4.0 on IsaClient gets its own design: to keep this experience, stay on 1.3.9 and don't update to 1.4.0 or later.
The rest of ZazaMod: Travel, Render, Cosmetic, Biome Spoofers and Audio Tweaks cheats
World Information tab: world data, bosses, invasions, seeds and utilities
The missing ZazaMod commands (see .help)
Fullbright no longer darkens lava and shimmer
New update server (client.hacks.win) with small hotfix updates

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.
