and that's why if your binding magic doesn't completely immobilize your target, you have to bind them limbs out stretched, to prevent the use of hidden tools, and gag them, in case of poison in the tooth trick AND to prevent any potential counter chants, it wont stop silent magic, but at least it'll limit their options more than just tying up the hands like this idiot did...or alternatively you can go with the "classic" fully knotted turtle-shell bondage style which wont come undone from one or two strands being cut (although it certainly looks better on females, so there is body type to consider...you don't wanna self destruct when on the verge of success)
