You know those pretty fireworks that pop when you open a coffin? Well, as per industry standard, we have entered a contract with the military and have now weaponised said fireworks, please enjoy! (we have not entered a contract with the military)
New weapon Greatest Jubilee: has a chance to create light sources (brazier, candelabras etc.) when firing. Scales with all usual stats, but works best with Luck.
To unlock it all you have to do is go for one of the new achievements of v1.0, "See the final fireworks."
