This would include encounter initiation, hp changes for the player, allies, and enemys(damage, mana usage, and recovery), boosts both permanent and temporary, from items(hp, mp, etc.) in combat, as well as skill stat influences(like $Str stat influencing attack score) with the battles flow, winning sequence(Rewards like exp, gold, items, etc.), and the player choosing what the allies do(Items, Special moves, Guard, Regular attacks, etc.) on ther turn(if they have any allies equiped in there party). Also returning to the "map" or place they were before the encounter(unless defeated of course).
Btw this will be a turn based game with the addition of having two or three allies to back up the player later on. also there is no particular death sceen when the player reaches 0 hp, rather the player falls uncontious and wakes up in a tavern bedroom, allies dont die for good either(similar to the player).
Us any name you want for the player, and us a Dark Elf or any other fantasy creature as the monster in your example to make it easier to understand please, and thank you. also i will specify anything if need be if you dont understand what exactly im asking for.
