Usage Notes

 * Read the article Interrupt for information on best practices when trying to interrupt a foe.
 * This skill is particularly useful to interrupt that last minute heal by a monk or a necromancer trying to save his/her own skin with a last second Orison of Healing or Life Siphon. Instead of a heal they get spike damage and probably die shortly after.
 * Power Spike has a recharge time that is shorter than most Mesmer interrupts. So it is very useful even with only few or no points in domination magic, especially if your build is not focused on interrupts but you still want to have some interrupt capacity.
