[1.6] manacoil + arcane combat bug

[east]

Manacoil no trigger on Lightning Arcane Combat.

1) confirmed that mana coil was triggered on the flame.

2) 100 Lightning average damage and maximum damage without mana coil.

3) Set the manacoil and confirm that there is no change in the average lightning damage of 100 times.

4) Maximum damage is also no change

Conclusion Manacoils don't trigger when setting up Arcane Combat Lightning. And it seems to be a bug.
