Rough translation of last Alkion's update:
Movement Order:------------------------------
This is still in conceptual stage, any opinions/ideas to improve the model would be appreciated.------------------------------
Lets say, one minute of game time consists of 100 units of discrete time. Every battle participant can take a turn(actions) determined by (50-agility+/-added effects) formula. For example a unit with action period of 38 (76, 114, 152) would end up with a speed of 2.6 or 26 turns every 1000 "timeunits". Queue of turns will be maintains for 300 timeunits under normal circumstances and updated as required by game logic.
------------------------------
For every turn, each character gets 4Action Points (this is Alkion so it's different than AP from PyTFall). Movings costs 1AP, Using item from a belt: 1 AP and accessing inventory 4 AP.
