FEF battle calculator requirements

The complete list of functions I need the Fire Emblem game to perform. This list is not in a particular order.

1. Track all statistics for multiple characters, saved in a character sheet that can be modified, stored, exported or imported.
2. Includes a weapon database featuring all the weapons listed in the player's guide, alleviating the need to input the information manually each time.
3. Allow for the creation and input of custom weapons. (As long as the editable database is in place and a couple test weapons are in place to make sure certain features work, such as weapons that change the number of attacks or apply statuses, the full weapons list isn't something that needs to be filled out by the person making the program)
4. Level up roll system. (Negotiable)
5. Keep track of whether or not personal skills/faults activate in a given conflict. (Can be based on character data true/false or checkbox method for things the program does not track like map data)
6. Set which combatant acts first in combat (Vantage notwithstanding)
7. Include support for the following Character skills: Adept(+), Blossom (if level up system in place), Awareness, Cancel(+), Counter(+), Fortune, Ignis, Luna(+), Miracle(+), Nullify(+), Resolve, Savior, Sol, Vantage(+), Weapon Saver(+), and Wrath(+).
8. Include checkbox features for the character skills Charisma(+), Gamble(+), Parity and Daunt(+) as well.
