You are adept at ensuring those that are bound by your hand stay bound.
When you tie up or restrain a creature by physical means, such as rope, manacles, or chain, any creature that seeks to undo or escape those bindings makes all ability checks and saving throws to do so with disadvantage. No effect or trait may allow a creature to make such checks with anything but disadvantage. Any functional locks you use for these restraints have their DC increased to 25, no matter the quality.
