Scroll: Elemental Mastery

You are keenly attuned to the elemental energies around you. For each element (Fire, Cold, and Shock) with full Focus charges, you gain additional mana regeneration per tick. If you attempt to consume Focus from an element that has 0 Focus charge, Focus will be consumed from a different element at a 2:1 ratio. If you run out of Focus between all 3 elements, the remaining cost is paid with your life force, damaging you for 10% of your Health per missing Focus charge. Additionally, when you cast a spell that costs Focus, you will generate 1 stack of Elemental Weaving, increasing your outgoing damage by 1% per stack. Stacks up to 10 times.
