Description
colossal is a structure mod that adds procedurally generated castles and dungeons along with normal structures. it's inspired by Better Dungeons/Chocolate Quest's randomized castle structures.
currently, it adds the "gray castles", a procedurally generated structure, and "mini battle tower" structure, with 86 variants (images above)
some things i was cautious of when i was making this:
they do not spawn everywhere and are also not impossible to find (use structurify if you don't like the rate)
they don't have op/trash loot
NOT easy to conquer

gray castles

mini battle towers. has 6 variants!

new: volcanoes! if you're lucky, they'll have a secret base within them that has a lot of loot. only way to find out it is to jump in it. gl (theyre a lil messy rn but theyre rare so youre fine)
this mod is still very very WIP, the generation might be a lil weird. im also planning to make the castles more "vertical" iykwim. plz feel free to share your suggestions and bugs in the comments
*the weird yellow blocks in the castles are supposed to spawn monsters but they kinda work half of the time so just kindly place a block next to them so they can spawn. play fair pls
upcoming:
basement level for gray castles n more room variants overall
other; ships, pirate island-settlements in the ocean, mountain infused structures, custom items & mobs.
upcoming structures:
a normal brick dungeon
a cousin of the nether fortress for overworld
procedurally generated "monster mansions"
rainbow castle, which only appear if you have my other mod Nature Equipped
all of these are incomplete
