This plugins changes how the damage of weapons is calculated. By default, weapons use the Strength and Magic stats for physical and magical attacks, respectively. But with the use of this plugin and some custom parameters on the weapon, you can change which stats are used for each weapons.
For example, you could make a weapon called Dagger that uses Skill instead of Strength, or uses a mix of 50% Strength and 50% Skill.
There is only one mandatory parameter, which is the "alternative" parameter. It has to have the 'true' value, so weapons can use the custom damage formula, which is described using all the other parameters. There is one parameter for each stat, and you can use one of them or more. You can even use no parameters, so the weapon doesn't use the stats from the unit and does fixed damage.
Each parameter must have as a value the percentage that the stat will be used. For example, 100 means that it will use the stat at its full value, 50 means half, 200 means double, and so on. Here is the list of parameters.
{alternative: true, spd: 100} 100% Speed.
{alternative: true, str: 50, ski: 50} 50% Strength and 50% Skill.
{alternative: true, res: 150} 150% Resistance.
{alternative: true} Only uses the weapon's might.
