Compressing Combat Supplies: Arrows and Bones
Arrow Chain
Arrow I through Arrow V are registered as both items and blocks. If you run a skeleton farm or a fletcher setup, you accumulate arrows faster than you can shoot them. Compress surplus arrows upward: base Arrow to Arrow I, Arrow I to Arrow II, and continue to Arrow V. One Tier V Arrow entry replaces an enormous number of loose arrows in your inventory.
Bone Chain
Bone I through Bone V follow the same pattern. Bones drop constantly from skeleton farms and are used for Bone Meal, so bulk bone is common. Compress Bone to Bone I, then upward to Bone V for storage. When you need Bone Meal again, break the chain back down to plain Bone and craft it into meal as usual.
Field Use
Because each tier is also a block, you can place a Tier V Arrow or Bone block in your base as a compact stockpile marker. Break it to retrieve the tier, then decompress. Both chains use the mod's registered crafting_shaped and crafting_shapeless recipes, so if the grid layout does not yield the next tier, try the shapeless form with the correct count of the previous tier in the grid.
