直接参考SA Compendium的五个问题就可以
Is it a magic item? 它是不是一个魔法物品？
Is it a spell? Or does it let you create the effects of a spell that’s mentioned in its description? 它是不是一个法术？它的描述里有没有提到会实现一个法术的效果？
Is it a spell attack? 它是否要求一次法术攻击？
Is it fueled by the use of spell slots? 它是否需要消耗法术位进行？
Does its description say it’s magical? 它的描述里是否提到它是魔法效果
气本身不属于任何一种，可以用。四象的炎蛇因为不是模仿特定的法术，只要原文里没提Magical也就可以用
主要容易被扯皮的点在于‘气之魔法’这个描述会不会导致武僧失去全部气相关的能力
这时候还是参考SA，因为魔法五问这段话上面还有一段话
You might be thinking, “Dragons seem pretty magical to me.” And yes, they are extraordinary! Their description even says they’re magical. But our game makes a distinction between two types of magic:
• the background magic that is part of the D&D multiverse’s physics and the physiology of many D&D creatures
• the concentrated magical energy that is contained in a magic item or channeled to create a spell or other focused magical effect
In D&D, the first type of magic is part of nature. It is no more dispellable than the wind. A monster like a dragon exists because of that magic-enhanced nature. The second type of magic is what the rules are concerned about. When a rule refers to something being magical, it’s referring to that second type.
简而言之，反魔场这类规则描述里提到“魔法”的时候，指的是规则描述部分里提到“魔法”的那些，背景描述里提到的“魔法”只不过是一阵风，不用去在意
