If the disintegrate must have its full effect, then that full effect comes in two parts:-
1.) do lots of damage
2.) after doing its damage, if the target has no hit points left, it is turned into dust (which is likely to be fatal)
#2 is incorrect. There is no requirement in the disintegrate spell that forces it to check after full damage has been dealt.
How do we know that we check for hp after doing the damage? Does anyone think that we check before we apply the damage?
False Dichotomy. It can check during damage, which is allowed for as disintegrate is written.
Damage, whether from this spell or a sword stroke, is done instantaneously as far as the game rules go. You don't do 12 points of damage from a sword and say, 'One hp; are you dead yet? No? Okay, another hp; that makes two. Are you dead yet?' This could take a while!
You do exactly that with Druid wild shape. Otherwise the druid could not revert at 0 and would have to revert at some sort of negative hit point total.
That's not how we play and it's not how the game reality works. If an attack-sword or spell-does, say, 80 points of damage then that damage is delivered all at once, not in one hp increments.
In general, no. With Druid wild shape, yes. That's how the game reality works with that ability.
So if a sword hits a wild shaped druid for 80 points, you check for unconsciousness/death after resolving that 80 points. In the meantime, the mechanics of wild shape mean that the 80 points lower the hp of the beast form until there are none left, at which point those remaining points reduce the druid's hp instead.
No you don't. You check each individual hit point of damage to see if the Druid hits 0. When that happens, the Druid reverts and you continue on. To save time, we skip the individual steps and just apply damage equaling the wild shape total, revert, and continue on. Disintegrate is the same. You apply damage equaling the total, "If this damage reduces the target to 0 hit points, it is disintegrated." (direct quote), revert the druid at 0, and continue on applying the rest of the damage to the ashed Druid.
It should be noted that when those 80 points from the sword stroke reduced the beast form to zero, the beast/druid never fell unconscious, never died. He reverted instead. That's how wild shape interacts with damage.
This is how you know that you are wrong. Reversion doesn't undo death. If the full 80 points was applied before reversion, the Druid would die from massive damage before he reverted. There is also no language in wild shape that allows for reversion to have happened "instead". It doesn't undo time. You are also flat out ignoring the wild shape rules that say that excess damage carries over to the reverted form, which directly contradicts your assertion that the 80 hit points of damage is not broken up.
