What a fcking joke this game is. First of all this isn't a Musou game but just an old school arcade beat em up added with gacha, Musou/Warriors games have objectives for you capture or special missions to do in order to progress thru a stage. As the stages gets difficult it rewards higher tier items or equipment. Dynasty Warriors Empires added Castle/Town building mechanics which is good although makes you feel a little ROTK-ish but its good.
