Equipment attributes are items that can be 'merged' with clothes (gloves,shoes,shirts, pants and head accessories) and give the tamer a boost in attack, defense, HP, DS and MS (movement speed).
Attributes need to be analyzed before they can be merged with equipment. This can be done at Kamemon [Equipment shop] in Western Village, Doruphin at Yokohama Village, Yokohama East Village and Village of Beginnings, Lillymon at Server Continent Desert and Server Continent Pyramid.
Analyzed attributes can be merged with equipment and extracted from equipment - only a certain percentage of merged attribute stats is applied to tamer stats - the percentage is determined by clothes stats.
Like all items, however, the drop rate for each item may change based on digimon’s level <—(however more evidence is needed to confirm hypothesis)
HP attributes can be merged with the [Jacket] equipment
DS attributes can be merged with the [Head accessories] equipment
AP attributes can be merged with the [Gloves] equipment
DF attributes can be merged with the [Pants] equipment
MS attributes can be merged with the [Shoes] equipment
