Treasure map (Dragon Quest IX)

A treasure map is a specialty item in Dragon Quest IX, which can be acquired in a number of different ways. When opened, a treasure map marks a particular spot on the world map where a secret grotto can be found. Treasure maps come in 2 varieties: normal and legacy boss. Overall, treasure maps play a key role in extending Dragon Quest IX's post-game by adding enormous amounts of additional content.

Methods to acquire

Tag Mode

See main article: Tag Mode

Treasure maps can be received via Tag Mode with other Dragon Quest IX games. When entering Tag Mode, each player is able to choose a single treasure map which they possess to share with other games in Tag Mode. This map will be "copied", meaning the original player does not lose it by sharing it on Tag Mode. This method of sharing treasure maps is also used for various Dragon Quest IX events in order to share maps.

Treasure Map Boss Item Drop

After defeating certain treasure map bosses multiple times, the possibility exists that the boss will drop a specific treasure map. However, only 5 bosses have the possibility of dropping a map and each of the 5 has a specific map which they drop.

King Schott

King Schott of Stornway Castle will give the player 1 random treasure map when speaking with him after completing the game.

Completion of a Normal Treasure Map

Each normal treasure map has a specific number of floors, always culminating with a boss monster on the final basement. Defeating this boss monster gives the player another normal treasure map. This is the primary method of obtaining new treasure maps, as there is no limit to the number of maps a player can complete. A new map is only given the first time a treasure map is completed. For information on how each normal map is generated, see below.

World Map Locations

Each treasure maps displays a location on the world map that the player must find in order to access the map's grotto/dungeon. There is a fixed number of possible world map locations where a map's grotto can appear. For almost all maps, the grotto location is randomly selected from all the possible world map locations. However, maps shared using Tag Mode or by completing quests retain the same world map location.

Types of Maps

Normal Maps

Normal treasure maps consist of a number of floors containing enemies and possibly treasure chests, as well as a boss in the final basement. The title of each map describes its level, which is a measure of its difficulty, as well as its overall theme. All normal maps which are not received via Tag Mode are randomly generated based on various criteria. See below for a full description of the normal map generation process.

Legacy Boss Maps

Legacy Boss maps are treasure maps which contain only 1 floor which holds a legacy boss from Dragon Quest I - VIII. These maps are considered bonus material and are only received using Tag Mode, by completing specific quests, and from other treasure map boss item drops.

Normal Map Generation Mechanics

After completing a normal treasure map, another map is randomly generated and given to the player. The mechanics of how a new map is generated are complex.

Step 1: Determining Quality

Quality is a computed number between 2 and 248 that is later used to determine how good the next map will be. A higher quality value yields more rare maps. The formula for quality is:

Quality = hero's highest vocation level + 5 * hero's highest number of revocations + level of previous treasure map

The hero's highest vocation level is the highest level they currently hold in any single vocation. The hero's highest number of revocations is the highest number of times they have used revocation in any single vocation. Note that revocation is the process used to change from level 99 in any single vocation back to level 1. 248 is the limit for any quality value.

Step 2: Grotto Content Generation

After computing the quality value, the game randomly selects one of 32768 maps for that quality value. Since quality can range from 2 to 248, there are over 8 million possible treasure maps! For higher quality values, the possible maps contain grottos which are much longer and hold more powerful enemies and bosses. The following table shows the relation between the quality value and the map difficulty.

Quality	# of Floors	Monster Rank	Boss
2-55	2-4	1-3	1-3
56-60	4-6	2-4	1-3
61-75	4-6	2-4	2-5
76-80	6-10	3-5	2-5
81-100	6-10	3-5	3-7
101-120	8-12	4-6	4-7
121-140	10-14	4-6	5-9
141-160	10-16	5-7	6-9
161-180	10-16	5-7	7-10
181-200	11-16	6-9	8-12
201-220	12-16	8-9	1-12
221-248	14-16	9	1-12

For each 4 floors traversed, the monster rank increases by 1. So for a map with monster rank 9, there will be monsters of rank 12 on basement 13 (9 + 12 / 4).
