List of skill anomalies
From Guild Wars Wiki
- Contrary to their descriptions, the following four skills affect the next attack made with an attack skill by each party member (or, in the cases of Anthem of Envy and Crippling Anthem, each ally). If an attack skill involves more than one attack, only the first attack will benefit. Since pet attacks work by applying a buff to the pet which is triggered by the pet's next attack, with neither the ranger nor the pet attacking directly with a skill, they are also unaffected. Because bears' Brutal Mauling skill is used by them directly, it will trigger them.
