代码是4722。第一分形原本的设定是游戏末期的近战武器，只不过在开发过程中被天顶剑代替。第一分形本来应该是目前版本的最强之剑，不过在开发过程中遭受弃用，它的代码还保留在游戏中，所以就成为了只能在代码中使用的武器了。
使用该武器时会召唤手持此剑的 15 种不同外观种类之一的、和玩家外观相同（但移除了所有染料效果）的射弹，跟随光标不断飞行攻击。如果附近有敌怪，此武器会自动以其为目标，并无视光标位置。
它无法在游戏中重铸。若使用物品栏编辑器，其最佳修饰语是虚幻，因为大小加成对射弹没有影响。
如果使用物品栏编辑器或相似方法将第一分形添加到人物的物品栏/研究菜单中，它会消失。这可以通过覆盖泰拉瑞亚的自动移除弃用物品的方法来避免，而后它就可以在单人模式和多人模式中正常使用。但如果将其存入收纳物品或丢出，它就会消失。
射弹人物没有染料是由于一个Bug，它在此物品被弃用前未修复。
第一分形的自动锁定目标的范围为 30 个图格。
我这里有。要加分哦。兄弟。下面就是JAVA的源码：
