Editing Treasure map (Dragon Quest IX) (section)

===5. Map name generation===
The treasure map name is generated based on the treasure map grotto contents and is structured as follows:

<pre>
prefix + environment + "of" + suffix + level

For example:
Clay Tunnel of Bliss Lv.1  
</pre>

Each portion of the map name represents an attribute of the grotto contents. Since the grotto contents are determined by the ''quality'' value listed above, the name is determined by randomly selecting from the eligible options for each portion of the name according to the grotto contents.
====Level====
The level formula is:
<pre>
|l| = ((f - 2) * 3) + ((m - 1) * 3) + ((b - 1) * 3) + r()
</pre>
or, to simplify:

<pre>
|l| = ((f + m + b - 4) * 3)  + r()

l: new map level
f: number of grotto floors/basements, not including boss floor
m: base monster rank of grotto
b: boss number
r(): random number between -5 and 5
</pre>

So for a map that has 8 floors (not including boss floor), monster rank 5, and boss 5 the level would be computed as:

<pre>
|l| = ((8 - 2) * 3) + ((5 - 1) * 3) + ((5 - 1) * 3) + r()
|l| = (18 + 12 + 12) + r()
|l| = 42 + r()
37 <= l <= 47
</pre>
So the level will be between 37 and 47, depending on the random value generated between -5 and 5.

====Prefix====
Prefix is related to the rank of the treasure map grotto. Rank is determined by the ''quality'' value computed above, and the prefix is randomly selected from the possible prefixes associated with the base rank.

{| cellpadding="3" cellspacing="0" border="1"
! Prefix !! Base Monster Rank
|-
| Clay || 1-2
|-
| Rock || 1-2
|-
| Granite || 1-2
|-
| Basalt || 1-2
|-
| Graphite || 1-4
|-
| Iron || 3-4
|-
| Copper || 3-8
|-
| Bronze || 3-8
|-
| Steel || 5-8
|-
| Silver || 5-8
|-
| Gold || 5-8
|-
| Platinum || 5-8
|-
| Ruby || 6-9
|-
| Emerald || 7-9
|-
| Sapphire || 7-9
|-
| Diamond || 7-9
|}
There is a fair amount of ambiguity with each rank, as a map with rank 8 could have 10 out of 16 possible prefixes.

====Environment====
Environment is the word in the treasure map title that describes the 'theme' of the treasure map grotto. There are 5 possible themes:
* Cave/Nature
* Ruins
* Ice
* Water
* Volcano
There are a variety of environment words used to describe each of these different themes. The environment word used is related to the number of floors the grotto contains.

{| cellpadding="3" cellspacing="0" border="1" style="text-align:center"
! # of Floors !! Cave !! Ruin !! Ice !! Water !! Volcano
|-
! 2-7
| Cave || Tunnel
| colspan="3"| Cave
|-
! 2-11
| colspan="2"| Mine
| Crevasse || Marsh || Mine
|-
! 4-13
| colspan="2"| Lair
| Icepit || Lake || Crater
|-
! 6-15
| colspan="2" | Path
| Snowhall || Moor || Dungeon
|-
! 8-15
| colspan="5" | Crypt
|-
! 10-16
| Nest || Ruins || Tundra || Waterway || Nest
|-
! 12-16
| colspan="5" | World
|-
! 14-16
| Abyss || Maze || Glacier || Chasm || Void
|}
The ambiguity is high related to number of floors. A grotto with 11 floors could have any environment word except for Tunnel and Cave.

====Suffix====
The suffix of the treasure map name is related to the number of the boss on the last floor of the grotto.

{| cellpadding="3" cellspacing="0" border="1"
! Boss Number !! Suffix
|-
| 1-3 || Joy, Bliss, Glee
|-
| 1-6 || Doubt, Woe, Dolour
|-
| 4-9 || Regret, Bane, Fear
|-
| 7-12 || Dread, Hurt, Gloom
|-
| 10-12 || Death, Ruin, Evil, Doom
