A Grotto is a dungeon that is revealed and accessible after sucessfully finding the correct location on a Treasure Map. Each Grotto has you navigating through a number of monster-ridden floors, and then defeating a Boss monster at the end for loot and experience.
 Grotto Attributes
Every Grotto has a unique level, name, type and number of floors. There are four types of Grotto:
- Cave (most common)
The level, boss and number of floors in the Grotto depend solely on what level Grottoes the player has completed in the past, the level of the party and how many times the player has revocated. The level range is 1-99.
The name of the Grotto is random, but is normally an indicator of what type of Grotto it is.
 The Grotto Bosses
Each Grotto has a boss. The bosses variate in difficulty depending on which Grotto it is. The bosses (in order of difficulty) are as follows:
- Sir Sanguinis
- Tyrannosaurus Wrecks
The bosses have no particular order of appearance.
