Katchin Shards are a crafting material, currently acquirable only through the use of Dragon Blocks.[verification needed]
Upon recovering seven Dragon Blocks, you can wish for Katchin Shards. If you wish for Katchin from Shenron, you'll acquire one Katchin Shard, whilst Porunga will give you three shards.
Katchin shards are essential in crafting the Brave Sword and Z Sword, the two later of the three swords in the mod. See the "Swords" page for crafting.
