Stealth skill?

I am looking to make a skill that makes enemies ignore the player unless they touch them, cause my enemies will be set to start battle when touched.

Basically it's like this, I want the enemies to be set to approach the player, but when this skill is used it should set them to random movements, and if the skill is turned off they revert back to trying to get near the player.

Trying to make a little sneaking segment.

This should be simple, add a extra page to the NPC(aka enemy) event, make it require a switch, and just have that page set to random movement.

Then all you have to do is make that skill call a common event that turns on the switch. 

Edit: whoops forgot you want it toggleable, do this

Ok I ran tests, and initially I couldn't get it to work properly, but no big deal, I got it to work, it was simple to fix.

You need 2 condition branches in the skill's common event, and this is how it is laid out:

Condition branch 1, if switch is off, turn switch on, then right after that, put exit event proc

Then after the entire condition branch, create another condition branch, except put if switch is on, turn switch off.
