How do you build and play a Soulknife Rogue?
Build the Soulknife on top of a normal Dexterity-focused Rogue, then invest in the secondary abilities and skills that support the archetype. Use Psi-Bolstered Knack on important proficient checks where the die can turn failure into success, and remember that the die is preserved when the boost still fails. Psychic Blades are excellent when you need concealed, disposable weapons, but magic items and resistance interactions may make a conventional weapon relevant in some campaigns.

How does Soulknife interact with Sneak Attack?
Psychic Blades qualify for Sneak Attack because they are finesse weapons. The first blade deals the larger damage die; the bonus-action blade is another opportunity to land Sneak Attack if the first attack missed and Sneak Attack has not yet been applied that turn.
