Threat

Threat is a mechanism in Dragon Age: Origins whereby enemies decide which characters in your party to attack.

Threat Level
Threat Level is the means by which a character's threat is deduced. Essentially, the higher threat level a character has, the more aggressive enemies will be towards that character, which will result in drawing more enemies to attack that character. The lower a threat level a character has, the more likely an enemy will seek out a different target to attack.
