Gods should use a wider array of solutions to fixing troubles. For instance, a god might give you a pile of corpses or food items that respect conducts you have kept rather than magically filling your stomach.

An ideal implementation would respect the gods’ personalities - e.g. if you’re low on HP and facing a lot of monsters, a “war god” could blast everything near you (but not you) with wide angle disintegration beams, while a “peace god” might pacify everything near you.

A tree hit by a fire ray or explosion should instantly incinerate, provided it’s not marked non-diggable (petrified). Likewise, a tree hit by a disintegration blast should disintegrate.

If someone of a different god steals the Amulet from you on the Astral Plane and sacrifices it to their god, your god will hit you with a wide-angle disintegration beam in frustration that you got so close and then blew it.

Disintegration rays have a small (on the order of 5% or 10%) chance of destroying the player’s reflection source instead of reflecting. This terminates the ray, so the player can’t get hit twice by it.

Erosionproof items should be immune to disintegration as well.

The scroll of destroy armor, when confused, cursed, and naked, grants temporary disintegration resistance.

Make instadeaths more consistent with respect to life saving: brainlessness destroys only the brain but cannot be life saved, whereas disintegration destroys your entire body but can be life saved. One or both of these should be changed.

Disintegration blasts shouldn’t reflect from a wall; they should dig it out instead. If the wall is undiggable, the ray merely stops - it never reflects unless it hits a creature who has reflection.

Dragon eggs should be usable as thrown missiles, having interesting effects on whatever they hit. Black dragon eggs should specifically have a disintegration effect.
