I can confirm that the Rocket artifact works based on the Base HPs of the targeted card (similar to dragon breath). Not based on its remaining HPs. It starts off at 20%. But until the data is provided here, I do not know what it maxes out at. I would guess 40% but maybe even higher. Hence, any targeted card that is down to its last 40% or less will be wiped out and your card opposite the targeted card will get a free shot at the mission HPs. It will be less impressive against Bosses, but probably better than most other artifacts, that gives you a chance at a free hit.

And unlike Fireball and Lightning it is run every turn. Giving you multiple chances of a free hit. (Assuming your card can last more than one round of course.)

I have noticed that the Rocket does not go off every single time. It is not mentioned in the description that it has a chance of failing to fire??? Not enough data to say for sure, but it appears to be maybe 1/3 of the time, maybe as high as 1/2 of the time the rocket fails to fire.

I do not know if it is working as designed, or if it is a bug that it some times fails to fire.
