Disgaea Mayhem Tools
Browser-based utilities to help you choose your weapon, track Item World runs, and calculate damage output.
The tools below are all browser-based, require no download or installation, and do not send your game data to any server. They are designed to run entirely client-side in JavaScript.
Weapon Affinity Quiz
Not sure which of the seven weapon types suits you best? The Weapon Affinity Quiz presents seven questions about your preferred play style, preferred enemy engagement range, and tolerance for complexity. At the end, it recommends the weapon type most likely to match your preferences.
This tool is particularly useful for players who are new to the Disgaea franchise or who are trying to decide between multiple weapons that seem equally appealing on paper.
Item World Run Checklist
The Item World Checklist helps you track your progress through Item World runs. Every piece of equipment in Disgaea Mayhem has an Item World with a fixed number of floors — normal items have 5 floors, rare items have 8 floors, and Legendary or Epic items have 10 floors.
This tool lets you mark which floor you are currently on, record the Enhancement Points you have earned, and track which item you are currently diving into. It is particularly useful when running multiple Item World sessions simultaneously, as the game does not provide a built-in way to log progress across multiple sessions.
Planned Tools
Additional tools are planned based on community demand:
-
Damage Calculator — Input your weapon type, skill level, enemy defence value, and Reincarnation rank to estimate single-hit damage output. This will help you compare weapons objectively rather than relying on feel alone.
-
Reincarnation Planner — Model different Reincarnation sequences to see how your long-term stat growth changes based on when you Reincarnate.
These tools will be added to this section as they are developed. Check the Updates page or follow the wiki on social media for announcements.
