I looked around the forums for quite a while and couldnt seem to find anything about scripting offensive (or hostile) force powers. I found a tutorial on it else and thought I would post the results of that tutorial here just so others might benefit from it. 
 
 NOTE: This is very, VERY basic and by no means set in stone but is definitely a good place to start

 #include 'k_inc_force' 
 
 void main() 
 { 
 object oTarget = GetSpellTargetObject(); 
 int nDamage = GetHitDice(OBJECT_SELF); //Will do 1 damage per force user level.
 effect eDamage = EffectDamage(nDamage); 
 effect eBeam = EffectBeam(VFX_BEAM_LIGHTNING_DARK_L, OBJECT_SELF, 
 BODY_NODE_CHEST); //(inspired by stoffe -mkb-'s Force Strike script)
 //effect eVFX = EffectVisualEffect(3001); Apparently this was lost in translation or the author of the previous file failed to mention something.
 ApplyEffectToObject(DURATION_TYPE_TEMPORARY, eBeam, oTarget); 
 //ApplyEffectToObject(DURATION_TYPE_TEMPORARY, eVFX, oTarget); See effect description for eVFX
 ApplyEffectToObject(DURATION_TYPE_INSTANT, eDamage, oTarget); 
 }
 
 
 Hope this helps and I apologize if any issues come of me posting this.

 SithAnnihilator is not asking a question, Lit ;). He decided to create a tutorial on how to script an offensive Force Power seeing as how one did not exist already. :)
