This is a simple datapack that solves the problem of megacaves having too many ledges that are hard to access without an elytra. You can grow magical glowberries that when eaten, shoots a beam that when it reaches a ceiling, drop down a cave vine that you can climb up and explore the higher reaches of the caves.

How to use:
1. Place a glow berry below a bone block.
2. Bonemeal the vine right below the bone block.
3. Collect the magic glow berry.
4. Eat them while looking at a high cave ceiling.
