I don't have a ton of experience with the CS and have next to no experience with scripting so if you attempt to solve my issue though script it would be great if you could just include the script I'd need (with variables at the point where you don't know the information, such as names of things).

Okay, so basically I created a spell set and now I'm creating a set of creatures. Some of these creatures are immune to some of those spells.
So, how would I go about creating a script for either....
1.) the spell, forcing the spell to just do nothing if it hits a target and the target's ID is equal to [whatever it's ID would be]
2.) create a script attached to the creature doing the same thing but essentially in reverse... so that if said spell were to hit it, the spell would be resisted completely.

Add a script effect to your spell with:

begin scriptEffectStart   if ( getIsID <editorIDofCreature )	  dispel <spellID>   endIfend

Thank you, so much!
