the title says it all, thank you for your time.

Theoretically 1: LivingHurtEvent - get source, check if explosion, cancell.

 

Theoretically 2: ExplosionEvent.Detonate - remove affected entities from List of affected ones.

no need to use events in ur own mob events are made to change vanilla behaviour.

 

u can override attackEntityFrom.

 

if the damage source is not explosive u can call the super method and let its do it thing, if its explosive just return true and ur done. 2 lines of code

thanks!
