RQ: spell based on slide

[onix_noob]

I need a spell that is cast by dummy unit at center of region. The spell will do the fallow things: terain must make move like water drop (it's not be so improtant to be equal can be similar) and units to be moved asside of the center, closest units to move more and those who are far away to move less (moving must be slide efect and the unit to can move toward the waves if is ordered by the player) also ability must make AOE dmg to units of type (units are structures) equal to 10% of their current hp (damage only be maked to friendly units) "i can do dmg thing myself i think". And one more thing at position of the casting unit must be created some lighting effect like thunderbolt from the sky
(and please if is posible make the trigger in GUI)
