Trolls are dumb, so confusing them is an exemplary plan of intervention. Even greater is running because trolls aren't really active in the initial position.

A thing to learn is the point that trolls are essentially magic animals and this, combined with their absolute capacity, means that they've made a sensitivity to witchcraft. A compassion that moves through their precious plasma. But that does not imply that they're not influenced by charms collectively. It only indicates that charms are limited on them so you have to use a ton of confidence to make a true charm work.

Stunning spells, for example, won't operate. Charms that are designated on the situation or charms chosen to hit it, by the aid of a large target, are presumably the safest chance.

The Bludgeoning Hex is a charm that creates a force on a designated section so, if you point it perfectly, you could cause enough impact on the troll to knock it out without using a heavy object.
