Was doing some exping last night using Mind Control and found a few things that seem strange.
The first was when I charmed Daggerspine Shorehunter ( http://db.vanillagaming.org/?npc=2369#wh-comments ) and used the ability Beast Tracking. I saw nothing happen so just assumed it didn't work. This morning I noticed I now have the permanent ability to track beasts just as I would flowers or treasure ect.
The second thing was occasionally when a MC would break, the mob just sat there. It didn't try to attack me back or run away; just sat there. It was a bit random so was hard to get it to repeat and try to see if I simply observed it wrong.
Similar to the second, occasionally when a MC would break, the mob I had charmed would continue to attack the NPC I was fighting. I charmed A, sent A to fight B, and when MC broke, A continued to fight B, while B attacked me.
Hopefully a few others have noticed something similar so can help clarify some of this.
