When to cast Knock

Almost never, and that is fine. If you have a Rogue with decent Sleight of Hand and a pocket full of lockpicks, this spell does not exist for you. It exists for the all-caster party, or the Origin run where nobody put a single point into Dexterity.

Two things it does that lockpicks cannot: it works from 18m away, and it never fails. A lock behind a trap you would rather not stand next to, or a high-DC chest that is about to eat your entire lockpick supply, is the moment Knock earns its slot.

It does not open magically sealed doors and it will not beat Arcane Lock. Better to know that now than to find out with the slot already spent.
