Ball of lightning not working?

[Elwin]

Ball of lighting is not just a direct damage spell, ots more like summon so u cant place it on other unit ;p

Ball of lighting attacks 3 turns, so its not a single troop cast ability, u need to cast it on a empty square near the troops u want to be damaged. Ball of lighting will attack random troops on each turn and it is supossed that the troops targeted are troops with high numbers stack.
