I found that Damage/Drain Speed works much better than Burden. It´s quite easy to lower NPC´s Speed to 0, which means they literally can´t move. Same goes with Strength, but they usually have more Strength than Speed.
Otherwise than that, just like Chris says. You´d need high magnitude of Burden and because the max Magnitude you can get is 100, it ain´t much, even with Weakness to Magic.
Frankl, it´s better to Drain/Damage their Speed or Strength.
