Terraria 1.4.5 Achievements Guide
Terraria 1.4.5 adds a batch of new achievements that focus on secret seeds, rare items, NPC interactions, and a few very Terraria style deaths. If you want full completion, most of these are straightforward once you know the exact setup, with only a few requiring long grinds or specific worlds. This guide lists every 1.4.5 achievement in alphabetical order and explains how to unlock each one cleanly.
How To Unlock All Terraria 1.4.5 Achievements
All achievements unlock automatically once their conditions are met. Most of them require specific secret seeds, world states, or items, so preparation matters more than skill. Journey Mode helps a lot, especially for testing setups and speeding up grinds.
