Power Spike

Description
If target foe is casting a spell, the spell is interrupted and target foe takes 20...86 damage.

Usage Notes
Usage is straighforward: watch for an enemy to start casting a spell, then cast this and watch their health disappear. If you would rather suck up their energy take a look at the sister-skill Power Leak.

Countering skills is tough at first, but once you get the hang of it interrupts will prove an effective part of your arsenal. It sometimes helps to have played the other spell casting classes so that you are familiar with their casting animations. When opponents are casting spells the skill name will appear under their name if you have them selected, but beware of depending on this because that skill will be displayed under there name long after your opportunity to counter has gone.

In a PvP match this is especially useful to prevent Monks from getting that last minute heal off to save their tank. Interrupt that critical heal and you may force them to try a Restore Life instead of a simple heal, not to mention that they will be hurt from your counter and so a great target themselves.

For PvE I wouldn't typically carry this skill, but really the same things apply as in PvP.
