Make "conjure lightning storm" rare modifier hits more accurate

Many times I encounter rares with this modifier. And I'm good with it.

My only complain is when the skill is unleashed on you, you can see blue sparks on the ground. But the lightning NEVER hit these sparks. Their locations is always random on that area.

In a game where dodge rolling is important, these ground spark should be something more meaningful, showing where the lightning will hit, so you can dodge away from them safely. They do too much damage to depend on luck to not be hit on last tiers map.
