1) On your way taking the first crystal to ghost hero, take out every minotaur that's there. You just cannot avoid them and it's better to eliminate three at a time than to have them all jump at you at once.
2) After skipping cinema, go through the left palisade gate and eliminate sage/arcanist group before the bridge. Inactivate splint mines whenever you encounter them as they are placed in strategic locations on purpose. Don't have to cross the bridge. If you want to cross bridge make sure you first eliminate 1 or 2 groups of sage/arcanist on the other side of bridge, because they often heal the boss that's guarding bridge, making bridge fight difficult. Always take out sage/arcanist group first as there's a healer boss randomly placed somewhere in this mission. Take out one group at a time and retrieve second crystal. Most ppl don't have problem with this part.
3) Now, for third crystal on the right. Do not, I repeat, DO NOT go through the right palisade gate. Continue through left gate as before, take the road behind the mountain (that road is there for a good reason
), so you don't have to fight patroling enchanted swords outside the right gate. If you have cleared enemies on your way to second crystal, you should not have to do any fighting. After going through that road behind mountain, you'll see a group patrolling near the exit of road, take them out (a must!). Then take out a group immediately on the left edge. After this, just turn left and then to the right through middle between two stationary mobs and avoid aggro either of them; the only group you have to take out now is the group guarding the vision crystal. After getting crystal, take the SAME road behind mountain on your way back. You should not have to fight at all on your way to give third crystal to ghost hero. So if you do this part right, you only have to fight three groups of enemies and none on your returning trip.So if you follow those three steps above, you'll still have 10 minutes left for bonus. Now, most ppl and PUG's fail this mission because they insist on going through the right gate and refuse to take that road behind mountain on their way to third crystal. Don't ask me why. If you keep running into groups like that, then getting henchmen is your best bet. The key is: never try to rush or avoid those enemies patrolling strategic route, one enemy killed is one fewer to worry about. But take out only those blocking your path and never tackle with those patrols that are too close to each other.
