To everyone wondering how to attack system works, according to reddit, the damage dealt to an individual with defense b, whose raider's attack is a, is equal to 10a / b. If b < 10, then b is set to 10 in this case, and if the total is less than 1 (10 * 5 / 500 = 0.1, for example), then 1 damage is dealt instead. Hope this helps!
