Fixed an issue where the health value would become negative as the level increased. These were held in int variables (up to 2147483647), but changed to handle long values (up to 9223372036854775807). In addition, the upper limit check of the long value has been tightened so that it does not become a negative value.
The same correction was made for Coin.
In addition, since it was found that the value would be larger than expected on the development side, the increase factor by character level / weapon level was reduced so that it was difficult to reach the upper limit. Since the factors for both health and weapons damage are reduced, the numerical value will be smaller, but the overall difficulty will not change.
