Speed (abbreviated SPD) is a statistic that affects the chance of dodging an attack. Speed can be effected by your monster's food choices (if you feed them too much, they may get fat and not be able to run as fast), which is a major factor in Monster Farm Online. It may also be effected by the sub-type that your monster has. For instance, Tigers and Rippers are known for being fast, but Golems and Thines are not. If your monster has a Golem sub-type, it will be slower because it is made of rock.
