With the inclusion of more Lemurian culture in the core game (and not mostly limited to the adventure module, Forgotten Fane of the Coiled Goddess), we've added the Lemurian deity Boetzu, which might fit what you seek:
BOETZU, “The Celestial Serpent”
Deity of Law associated with the sun, light, law, agriculture, society, protection, duty,
enlightenment, and the circle of life. Boetzu is said to manifest in the guise of a gargantuan,
serpentine dragon, or as a grizzled old sage.
Typical Clergy: clerics, monks, paladins, priests, shamans
Typical Followers: any (esp. Lemurians)

For combat, we were more easily able to spell out the things you can do within the framework of these broad categories: melee, missiles, magic, movement, and other actions.
While we don't have specific simulations spelled out in detail (i.e., Billy's cataphract makes a charge attack with a long spear. although his side lost initiative, and the lizard-man javelin wielder should go first, the referee is using the first strike rule, so Billy's cataphract gets to go first because of his weapon's larger weapon class), I do feel that the format and explanatory text makes each aspect of combat much more understandable than in previous editions.
