Trip is an ability to knock-down an opponent. It is very useful when fighting certain enemies of the same size as heroes. Golems and certain bosses seem to be immune to this. This is not the only ability that can knock down the opponent, there are more others. Furthermore, it is a main ability that can only be learned once. It can however be enhanced with another skill such as the Improved Trip ability.
1/1 : Knock a target to the ground for 5 seconds, reducing its defense by 5%.
