A hero cast raise dead and explosive arrow

[Herod]

Im making a rpg, but having troubles. A necromancer hero raises deads like in diablo 2, no idea how make this hero abilitie.

And other ranger, fires a imolation arrow that causes damage of area and a burning oil effect, no idea how do too.

And the skeletons raised how make they follow hero (they are incontrolable like in diablo 2). TY

The raise dead i got it ! Lvl 1 raise 1 skeletons lvl 2 2 etc..... but the follow trigger is bad. The skeletons always stay behind the necro and not front
