What it should do: When you deal damage with a melee weapon, you have a chance (higher than rank 4) to reduce the cast time of your next Lightning Bolt, Chain Lightning, Lesser Healing Wave, Healing Wave, Chain Heal, or Hex spell by 20%. Stacks up to 5 times. Lasts 30 sec.
What it does: Nothing xD - spell needs to be tweaked to adapt to the 0.00 attack speed. At 0.00 it will not proc unless changed in core.
