When your hero faces an obstacle or risky endeavor, one that carries a risk of failure, injury to a hero, or dire consequences, this requires the hero to Overcome the challenge.
Assemble your dice pool, roll those dice, and then compare your result to the following list: When your hero takes a twist, you as a player decide if you’ll answer one of the questions under your principles (if appropriate to the scene) or you can let your GM decide an appropriate twist. A twist is always that: a plot twist, so work with your GM to determine an event that makes the story more interesting and moves the plot forward. If your hero tries to deals damage to another character, whether it’s physical (a series of punches), emotional (mocking taunts), or mental (psychic blasts), that’s an Attack.
Assemble your dice pool, and inflict damage to your target equal to that result. If the target is a character with a Health rating, they lose that much Health. If the target is a minion, they roll a minion save to see if you knock them out immediately or not.

When you Boost or Hinder, you make an effect called a mod. The Boost action creates a bonus for you or an ally; the Hinder action creates a penalty for an opponent.
Assemble your dice pool, roll those dice, and then compare your result to the following list to determine the mod size:
Any number of bonuses and penalties can be applied to a roll, except only one exclusive mod can be used on a roll. Bonuses or penalties only apply for one roll and then go away unless they are persistent or an ability dictates their duration. Your hero is always taking steps to protect themselves, but there are times when they want to focus on protecting themselves or someone else. In a Defend action, you describe what your hero is doing to avoid or reduce an Attack. Assemble your dice pool, roll those dice, and note your result. When you or the target you are Defending would next lose Health before your next turn, reduce the amount taken by your Defend result. If you or the target you’re Defending are not Attacked before your next turn, the effect is wasted.
If you are under the effect of multiple Defend actions, choose the higher result to use; do not combine them.
