Extract files from Erenshor.TreasureMapOverhaul.zip into Erenshor\BepInEx\plugins\ folder.
Changing Drop Rate
Run Erenshor so the config file will be automatically created
Open et508.erenshor.treasuremapoverhaul in your Erenshor\BepInEx\config
Change values to your liking
I recommend using a config manager like BepInExConfigManager for easier config changes from ingame
The Treasure Maps
This mod will replace any treasure map corners you currently have with the new "A Torn Treasure Map". In your bank and your inventory.
Removes the old corner maps from the loot tables and replaces with the new map.
Changes the quest turn in for a Treasure Map to 4 of the new "A Torn Treasure Map". No more hunting down corners or stock piling 1 type and never seeing another.
This does effectively remove the old map corners from the game. So if you use this mod and then remove it you will lose what maps you had.
Erenshor LootTables
If changing drop chance using a ingame config manager, changes to drop rates will only apply to newly spawned enemies. Reload the scene or wait for new respawns for changes to apply.
