How do you create a unique enemy npc in CK?

[AvGeek]

I am planning to create an enemy npc that changes level with the player. Like if the player is lvl 10 the enemy is lvl 15 or the player is lvl 50 and the enemy is lvl 75. I know the Template data provides an AcotrBase that can do that with the prefix "lvl" but the problem is that it removes the Unique npc option. So is there a way to create a Unique enemy that levels up with the player?

Create a new NPC from scratch.

 

Check the "unique" box, then go to his Stats and tick the box "PC level Mult"

 

Then insert the multiplier you want, and also insert a min and max level for this NPC

 

For example if you put 20 in the "min" field, if you're at level 1 ths NPC will be level 20.

What factions and ai data or packages should I use for it to turn aggressive on me?
