This plugin has two major changes;you need a block to break one, and land claims are done using lecterns and books.

Getting Blocks
You might be asking, “How am I supposed to get blocks?”
- Logs from trees are always mineable.
- Ores are always mineable.
- Pigs and skeletons drop dirt and stone
- And many more left for you to discover!

Lectern Land Claims
Place a book, with you and your friends names in it, in a lectern, to protect a chunk. Surrounding your lectern in unique block combinations is essential to protecting your claims, so use TNT or creepers to blow some up!

Builds take effort to destroy and Conquering land is intuitively made with PvP and freedom in mind.
