With this mod, you can register a map file to be used for the mines and / or Skull Cave; it will be added to the list of randomly selected floor maps.

You can force a map to be used for a specific floor, or set minimum and / or maximum levels for a map to be used on.

Custom maps will never be used for floors divisible by 10 (or 5 in Skull Cave, though idk why).

To register a map, use Content Patcher, following this example:

{
"Format": "1.23.0",
"Changes": [
{
"Action": "EditData",
"Target": "aedenthorn.AdditionalMineMaps/dictionary",
"Entries": {
"aedenthorn.AMMCustom": {
"mapPath": "Maps/Mines/aedenthorn.AMMCustom",
"minLevel": 121,
"maxLevel": -1,
"forceLevel": -1
}
}
},
{
"Action": "Load",
"Target": "Maps/Mines/aedenthorn.AMMCustom",
"FromFile": "assets/AMMCustom.tmx"
}
]
}


Set any of minLevel, maxLevel, and forceLevel to -1 (or just omit them) to ignore them. Level number for Skull Cave starts at 121.
