He's also using dictate to charm, which has a fixed duration. Not sure how /q reacts to random duration charm spells.

ya fixed duration spells of any kind should maintain fucntionality regardless if you are logged in or out. Random duration spells are supposed to fall off the first tick after you are regstered as having logged out. it's classic though the second part of this doesn't appear to always work correctly and the spell sometimes stick around a bit longer than they should.

This. Simple as that.

Nothing snarky about it! It is genuinely interesting. I love seeing players who think outside the box.

As for how to do it KoS, it's nothing special, just the standard way we did it back in the day. This video shows it - note how he /q's at a certain spot. Therein lies your answer.

Nice video OP, well done.

thank you… to be perfectly honest, all respect goes to someone else (I cant remember the name.) One day I was exploring SG out of boredom when I saw this guy charming and fighting this heavy shit stuff. I was in admiration although I didn’t really quite get it. How was he really doing ? I spied on him for 3h and started to understand. All the beauty lies in Dictate. I always thought this spell was a gimmick : what the fuck you do with such a short duration? Well, I learned dictate enables next level enchanting. Charm a 280+ quad hitting total monster to smoke a target in under 50 seconds, thats where the magic is. Combine this with clever out of the water safety, /q faction mechanics, behind the pillars safe relogging and you got a super fun solo camp. This place is basically the best plat per hour in the game (that Ive seen at least). Next I’ll show how to make spawn shimmering sea spirit. A much tougher and nerve wracking camp

Both non-fixed duration high level charm spells (like Boltran's, Allure, etc) and root spells will hold after you /q out. Often the longer root spells will still be on a mob when you log back in, though the charm spells will always end before you are able to log in.

Very helpful answer from the person who supports cheating using third party programs

How do you get there when being KoS? There are multiple see invis stuff everywhere
