For my IF site, can I use a battle system similar to FEW?

It'll go somewhat like this:
Vitals:
Attack Strength
Attack Chance
Block Chance
Miss Chance
Armor
Outside Protection

and the new stats will be similar to FEW.

I will post saying that my battle system is derived from Fire Emblem Wars and I will advertise it there.

Please answer quickly.

You can use anything you want that comes from FE, but not our character system, house system, war system, etc.

House system meaning like house names of having a house/country in general?

Well, I guess our house system is sort of generic. Just don't blatantly copy us.

Ok, I won't. Thanks a lot, I can actually progress now!
