An entangle that doesn't need magic though. Maybe its got a reeeeally sticky toffee filling or something. Ooh I know! Magic! magic apples. In the pie. Yep. Magic.
When I first started out in runescape I attacked a lvl 2 man in lumbridge by accident. I didn't think it was an NPC so I was running away going "sorry, Sorry OMG Sorry". That's probably the noobiest thing I've ever seen anyone do since!
I don't really know the reason why they've done it. I can only hazard a guess that it's to do with some law or other. Plus I don't think the young 'uns are as likely to be paying members.
I suppose it's to cover them on from a legal point of view. Now the content can be 13+. I don't really know what i'm on about really but it probably makes sense.
