Are there any other practical reasons for choosing proficiency in Intelligence saving throws, other than seeing through illusions?
It was suggested to me to take the Resilient feat. I considered taking Intelligence, but I can only think back to a handful of occasions where I used an Intelligence saving throws and it was always to do with illusion magic.
Choose one ability score. You gain the following benefits:
Increase the chosen ability score by 1, to a maximum of 20.
You gain proficiency in saving throws using the chosen ability.

I mean, other than to have a better chance of seeing through an illusion spell, is there any point in having a proficiency with Intelligence saving throws?
It seems like it is the least useful out of all the saving throws proficiencies.
Dexterity, Wisdom and Constitution get used the most; Strength and Charisma less so, but Intelligence…
Of course, if you are in a campaign where illusions are very common, then yes I can see how this could be very beneficial, but for most campaigns I can’t see the point.
Are there any other uses for the Intelligence saving throw, such as to counter a monster’s special ability (other than an illusion)?
This is a question about saving throws, not ability checks.
