Waterbolt is a relatively rare magic weapon in Terraria, generated during world creation, with a 1% chance for any given Dungeon platform to hold it.
Understanding Waterbolt Rarity in Terraria
The rarity of the Waterbolt is determined by a two-stage probability during the world generation process, specifically within the Dungeon biome. This means its appearance is not guaranteed, and finding one often requires exploring multiple platforms or even multiple worlds.
Here's a breakdown of how its rarity is calculated:
-
Step 1: Book Placement Chance
Each platform within the Dungeon has a 1/2 (50%) chance of having any type of book placed upon it. If a platform fails this initial check, it cannot contain a Waterbolt. -
Step 2: Waterbolt Transformation Chance
If a platform successfully generates a book (from Step 1), there is an additional 1/50 (2%) chance for that specific book to transform into a Waterbolt.
Combining these two independent probabilities reveals the overall rarity for a Waterbolt to appear on any single Dungeon platform:
- Total Probability per Platform: (1/2) * (1/50) = 1/100
This translates to a 1% chance for any individual platform in the Dungeon to contain a Waterbolt.
Rarity Summary
| Event | Probability | Percentage |
|---|---|---|
| Platform has a Book | 1/2 | 50% |
| Book is a Waterbolt | 1/50 | 2% |
| Total Chance per Platform | 1/100 | 1% |
Given that the Dungeon contains many platforms, it's common for players to find at least one Waterbolt during their exploration, but its specific location can be elusive due to this low per-platform chance. Players often search through numerous platforms or create multiple worlds if they are specifically looking for this early-game magic weapon.
