The mod adds new variations of the lantern block which can be crafted at a lantern maker altar. Every lantern type has a special effect like increase crop growth, withering, slowing nearby mobs, and many more! To get started with the mod you will need to craft "Lantern Codex" which gives information about each lantern (crafting ingredients and effects) after gathering all the ingredients and putting them into an altar you can place a vanilla lantern on top to complete the crafting process!
This is a fabric mod!
