The Department for the Regulation and Control of Magical Creatures gives classifications to all known beasts, beings and spirits. These offer an at-a-glance guide to the perceived dangerousness of a creature. The five categories are as follows:
神奇动物管理控制司对所有已知神奇动物、人及幽灵建立了分级系统。这样一来，这些生物的危险性便一目了然。下面是五种分级：
Ministry of Magic (M.O.M) Classification
魔法部（M.O.M）分级
| XXXXX | Known wizard killer/impossible to train or domesticate | 众所周知的“巫师杀手”/无法调教也不能驯养 |
| XXXX | Dangerous/requires specialist knowledge/skilled wizard may handle | 危险/需要专业知识/资深巫师可应对 |
| XXX | Competent wizard should cope | 普通巫师足以应对 |
| XX | Harmless/may be domesticated | 无害/可驯服 |
| X | Boring | 无趣 |
In some cases I have felt an explanation for the classification of a particular beast is necessary and have added footnotes accordingly.
我觉得有时候得解释一下某个特定的神奇动物分级，所以我在对应的地方加了脚注。
