The boost/drain of this prayer will take anywhere from 1–3 minutes of continuous combat to maximise. This prayer is extremely useful against powerful, high-defence monsters such as Mithril dragons, or in PVP situations, and is proven highly effective when used against Nomad in the Nomad's Requiem quest. Because the Defence drain/boosts will reset after each kill, this curse is most commonly used against boss monsters which take a long time to kill, however it is still somewhat effective against lower-levelled monsters.
