Nemo’s Mossy Vertical Slabs Mod (1.21.5, 1.21.1) introduces moss-covered vertical slabs, offering a fresh aesthetic for builders who love blending natural decay into their designs. Acting as a compatibility bridge between Nemo’s Mossy Blocks and Nemo’s Vertical Slabs, this mod merges features from both to expand your decorative options.
Instead of relying only on full blocks or standard mossy stone bricks, you now have the flexibility to use mossy vertical slabs perfect for ruins, overgrown temples, or organic builds. These vertical slabs occupy half a vertical block, and when placed together, they combine to form full structures or complex shapes. It’s a small addition that makes a big visual difference.

Features:
- Adds mossy versions of vertical slabs based on common stone and mossy block types.
- Allows for combination slabs two or more slabs placed together form cohesive structures.
- Integrates seamlessly with both Nemo’s Mossy Blocks and Nemo’s Vertical Slabs.
- Fully compatible with Fabric loader.
