I've been looking for a way to let players change the damage type (elemental/poison/physical) of their staff by using new recipes. Making the new recipes was easy, but the rest is proving to be difficult.

The first thing I did was copy and modify the Poison_Staff ItemCombo and change the copies' names and item req's in the Stats Editor. After that, I did the same thing with _Boost_Weapon_Crafting_Damage_Poison under Weapons. The problem is that I can't seem to get rid of that original damage type. If I go in-game and use my new recipe to change my water staff to a physical one, the result is a staff with equal amounts of water and physical damage. If the original weapon had 20-24 water damage, the new one has 20-24 water damage and 20-24 physical damage.

Is it possible to use new ItemCombos and _Boost... to let users change their staff's damage type with new crafting recipes, or do I have to take another approach?
