This skill allows you to imbue elemental materials with spell effects. This means that the material that you gave an elemental property to can now cause a spell effect. For example, if you grant some steel the elemental property of life, you could then give it the magical effect of lightening strike, allowing you to make a sword for example of that steel that causes lightening strike spell damage with a critical hit. The metal can only hold so many charges however. The amount of charges you give the metal is 1 charge per 2 Soul.
