Basic combat is your typical weak and strong attack combat like musou but the movesets are more combo oriented, enemy designs are more like other action games where there are blockable and unblockable attacks that will give you yellow/red flashes you need to avoid. You have special moves that can be mapped to shoulder + face buttons, they give different properties from multi hits combo to attacks that knock down crowd or return health etc, after certain # of hits you could use a finishing move that does big damage, so you usually would try to keep the combos up. And then you have a counter slash that you can do by pressing block when enemy attack lands.
The game has some minor stamina management where block/dash/teleport will drain up your stamina, so you sometimes need to play defensively and know enemy patterns and counter/stagger them to your advantage.
You also have the dpad buttons to slot in teammate and pet special moves.
I think it's a fun combat system if you like hack and slash games, honestly not many out there that isn't a souls-like these days
