After beating Plantera and Golem in Terraria, Martian Probes spawn, Old One's Army ascends, and new items become available from NPCs.
Beating Plantera and Golem in Terraria is a significant milestone that unlocks new events and vendor items.
Tips
- Martian Probes will spawn on the outer edges of your world, near the ocean. Allowing them to scan you will trigger the Martian Madness event.
- The Old One's Army event will ascend to its third and final tier, which is the most difficult.
- The Steampunker NPC (non-player character — anyone the game controls, not you) will now sell Steampunk Wings, which are powerful and easily accessible wings.
- The Party Girl NPC sells the Celebration rocket launcher. While nerfed in version 1.4, it still has uses. It disables unique rocket effects but retains a large firework area of effect (AoE) useful for searching for ores or other items due to the light emitted. It also will not damage you if used near yourself.
