Better Stat Drain (STR, DEX, CON, INT, WIS, CHA)

I've long been fascinated by the Strength drain effect of Called Shot, the Dexterity drain of Haer'dalis' Chaos Blade, and the Intelligence drain of the mind flayer attack from Shapechange. They were a very unique method of killing enemies that bypassed immunities.

Then EE removed the exploit by making plot-immune critters impossible to kill via stat drain. This prevented the player from accidentally breaking the game by killing a character played a critical role in the plot, but it also made stat drain useless against all kinds of bosses. One of the coolest ways of winning a fight had suddenly become rather limited.

This mod changes that. It doesn't allow you to kill plot-immune critters, but it does allow you to win a fight against one just by using stat drain. If you reduce any ability score of a plot-immune critter to 1, they will drop to 1 HP and trigger any dialogues or scripts or cutscenes that are supposed to trigger when you defeat them. Kudos to @subtledoctor for making this mod possible.

The mod is attached below. Currently it has only undergone the barest of testing.
