Does the Rogue's Reliable Talent work for thieves' tools, since the rogue is proficient in them?
On PHB, pg. 96, it says when Reliable Talent is applicable:
Whenever you make an ability check that lets you add your proficiency bonus
And on PHB, pg. 154, it says about using thieves' tools:
Proficiency with these tools lets you add your proficiency bonus to any ability checks you make to disarm traps or open locks.
Based on this phrasing from the PHB, I believe it would indeed work for tools and kits, but I am looking for affirmation of my understanding.
