We use the game mostly RAW. Here are some of the changes we use at my table.
A small boost in elemental damage from Foundation. It feels nice to have an special D8 in your hand as your Elemental Die, the color of your element. Yes, this is totally an excuse to have more dice.
FOUNDATION FEATURE
Elementalist: Choose one of the following elements at character creation: air, earth, fire, lightning, water. You can shape this element into harmless effects. Additionally, spend a Hope and describe how your control over this element helps an action roll you’re about to make, then either gain a +2 bonus to the roll or 1d8 bonus to the roll’s damage.
Added a second feature at specialization to enhance Tag Teaming.
Refined Manipulation: You can use your “Manipulate Magic ” feature on an ally’s spell when you initiate a Tag Team roll with them.
