Overcharge: When you spend Spark to Help an ally on an attack and it succeeds, roll another die of the same size as your Spark die and add the result to the damage dealt to one target.
Reverse Engineer: Once per scene, when you study a creature, device, or magical effect, ask the GM one question about how it functions, what it can do, or how it might be disrupted. The GM answers truthfully. The first action roll that acts on this information has advantage.
Feedback Loop: When an attack enhanced by Overcharge deals Major or greater damage, the target becomes Vulnerable until the end of their next action. If the attack deals Severe damage, gain 1 Spark.
Perfect Calibration: When you roll bonus damage from Overcharge, roll two Spark dice instead of one and add both results to the damage.
