2. What thief stat, introduced in "Quest For Glory 3," is useless in "Quest For Glory 5" unless you use the hard method to get the Pegasus feathers?
From Quiz "Quest For Glory 5": Sneaking and Stealing
Answer:
Acrobatics
The thief learned acrobatics from the rope vendor in Tarna in "Quest For Glory 3." It was useful for tight-rope walking in that game. It was also useful in "Quest For Glory 4," helping the hero get through the swamp and helping the hero escape some of the traps that come up after reading some of the rituals in the Dark One's cave. But you don't need it in "Quest For Glory 5."
The one place you can use it in "Quest For Glory 5" is Pegasus Peaks. If you have the rope and grapnel when you're at Pegasus Peaks, the seesaw won't be there. You'll have to use the rope and grapnel to go from one rock to the other. You can't do this unless you have very high acrobatics. If your acrobatics are a little too low, the hero will walk to his death. If your acrobatics are WAY too low, the hero won't even attempt the walk. You could keep repeating attempts to do that tight-rope walk and build up the Acrobatics stat, but all that's going to happen when your Acrobatics stat gets high enough is the hero will walk to his death. The only other place to get an Acrobatics' boost is in the water. If you swim for a little while, you get a temporary major boost in Acrobatics. However, this is very inconvenient to do and you won't be able to get the water-breathing amulet before you need the Pegasus feathers so you will unnecessarily lose some health and stamina if you try this. And if you put enough points into Acrobatics at the beginning of the game that the hero can do this walk successfully from the start, you've just wasted a lot of points. There is a better way to get to the Pegasus nest, acrobatics are completely useless elsewhere, and every other stat is far more useful in this game.
If you get the rope and grapnel before going to Pegasus Peaks, you should put it in you chest before going there. Then, the seesaw will be there. It's MUCH better to use the seesaw to get past that part.
