Leech Signet

Description
Interrupt target foe's action. If that action was a spell, you gain 3...13 Energy.

Usage Notes

 * This signet interrupts all skills, not just spells. You won't receive the energy gain if you interrupt something else with it, but it's good for interrupting skills such as Resurrection Signet.
 * As it doesn't count as a spell itself, it is useful for interrupting spells after an enemy Mesmer has cast Backfire on you to prevent you from stopping their next spell.
