# Clue bottle

Clue bottles are bottles that can be found while training Fishing. Opening them will destroy the bottle and leave players with a clue scroll of the same difficulty as the bottle given. Players will not receive a clue bottle if they possess a clue scroll of the same difficulty tier. Like clue scrolls, players can only have one of each type of clue bottle in their possession.

There are five types of clue bottles:

## Rates

Like skilling pets, the rate of obtaining clue bottles are dependent on the player's fishing level and the type of fish the player is catching. A ring of wealth (i) will double the rate of clue bottles for fishing spots in the Wilderness.[1]

The chance of obtaining a clue bottle of any difficulty is ${\displaystyle [(100+Y)/X]}$, where ${\displaystyle Y}$ is the player's fishing level and ${\displaystyle X}$ is the base chance of the fish. Equivalently, this chance is 1 in ${\displaystyle [X/(100+Y)]}$. For example, a player catching anglerfish at level 99 fishing will have a 1 in 395 chance of obtaining a clue bottle, with decimal values floored.

The table below displays the base chances of obtaining a clue bottle; all rates are confirmed by Mod Tide.[2][3][confirmation needed] It is unknown exactly how Combat Achievements affect these rates.
