Using Kairoseki and Poneglyphs
Mining and Processing Kairoseki
Kairoseki Ore and Deepslate Kairoseki Ore generate in the world. Mine them with a pickaxe to obtain raw kairoseki material. Smelt or craft the raw material into Kairoseki Block, Kairoseki Bars, or Dense Kairoseki. These blocks are used to build restraints and structures.
Kairoseki Bars function as a prison-style block. Dense Kairoseki is a heavier variant for tougher builds. Use Explosive Handcuffs alongside kairoseki to restrain targets. Place Kairoseki Block as a solid building material where you want a sea-stone aesthetic.
Reading Poneglyphs
Poneglyph and Road Poneglyph are placeable blocks that carry lore text. Place one and interact with it to read its inscription. Road Poneglyph is the rarer variant tied to navigation lore. Both are decorative and informational rather than craftable through normal recipes — you find them in structures or obtain them through admin commands.
Combining with Other Blocks
Pair kairoseki builds with Ori Bars for a cell-like structure. Flag and Wanted Poster blocks let you decorate a base or bounty board. Wanted Poster Package bundles posters for distribution. String Wall and Barrier blocks add containment options. Together these blocks support player-built prisons, marine outposts, or pirate hideouts.
