Ion Overcharge Capacitors
When a ship with this upgrade activates, place a blue die on this card. You may use this die pool for any attack against a ship, regardless of range. If the die count exceeds 3 at any time, roll the accumulated dice. Deal any damage to yourself, ignoring shields. Then, discard this upgrade.
Sort of like Viperous' Ion Particle Reactors upgrade, except it allows you to accumulate dice. However, if you don't use the accumulated dice pool, the capacitors 'forcefully discharge', potentially damaging the ship.
