SSE Link an effect or a spell to a creature's critical hit ?

[arael53]

Hello,

 

I'm looking for a way to link an effect to a creature's critical hit, similar to the possibility to add an effect triggered by weapons critical hits.I want some creature to only apply their effect (poison, etc...) on a critical hit.

is there a way to do something like this ?

 

Thanks for your help !

 

Edit: Can I modify the creature race combat data to make them attacking with sword, create a new unplayable and invisible sword, and attach the spell to hit ? Could it work without looking weird ?
