Migraine

Usage Notes
Especially useful in PvP - casting Migraine on an enemy spellcaster can give them a real headache in a hurry. The main point of this hex is to give you and your allies a significantly larger time window for interrupt skills like Power Spike or Distracting Shot. Most victims to a combo like this will stop trying to cast spells entirely after just two or three consecutive interrupts.

The weaker form of this hex, Arcane Conundrum, doesn't cause health degeneration, has a shorter duration, and has a longer recharge time. In contrast, with 12 rank in Illusion Magic, Migraine can be kept on a target indefinitely as long as the mesmer has the energy available for it. However, when both Migraine and Arcane Conundrum are used, the enemy will be even more frustrated, and even skills which cast nearly instantly, such as Reversal of Fortune, are interruptible.
