Events are unique occurrences that provide interesting gameplay elements, such as new enemies and drops. Thorium adds a few things to existing events, increasing the amount of content the game offers.
Blood Moon
- Main article:Blood Moon
Several new enemies are added, including a mini-boss, Patch Werk. Completing at least one Blood Moon and defeating Patch Werk is necessary for the Confused Zombie NPC to move in. Completing a Blood Moon is also essential for the progression of a Healer character, as an important Healer item, Unholy Shards, drops from Blood Moon enemies and is necessary to craft core Healer items. In addition, the Blood Moon Medallion allows the player to summon a Blood Moon on any night.
Rain
- Main article:Snow
During Hardmode Blizzards several new enemies and a new boss called the Borean Strider may spawn. The Borean Strider has fast attacks and may prove challenging for unprepared players, but it drops several ice-themed weapons that make it worthwhile to fight. It also has an Expert Mode exlusive Treasure Bag. The Rain Stone allows the player to make it Rain at will.
Holidays
2 new items, the Halloween Spirit and Holiday's Greeting allow the player to activate Halloween or Christmas respectively, causing the seasonal drops and enemies to appear as though it was that time period.
