I have been working on a plugin that creates new kinds of armor with special effects. The special effects part is all good and well but I am struggling with changing/calculating damage for the leather armor type. I have been messing around with the Entity Damage Event to try to change the damage a player receives when they are wearing leather armor. I am trying to make the leather armor a little bit stronger than diamond and I have tried looking through the java docs and looking at multiple sources but they have not shown me the path to a solution. Any help or suggestions would be most pleasing.
