1. What's with the blue and red brackets when the flying things come near. There are either 1 or 2 blue or red brackets or 1 red and blue at the same time.
I just answered that on my former post.
2. Why doesn't the dragon regenerate hp like the human
He does, but slowly (like the human in the beginning). You may want to put points in the healing spell, or equip potions.
3. How do you unlearn dragon skills. You have to be human to talk to the trainer and then you can't access dragon skills.
The trainer makes you unlearn all skills, dragon and human.
4. What is the deal with target lock. There are keys that say target lock in options but they don't seem to work
It works fine on my computer, so I don't know what to say. The paper manual is wrong with the key, though, so you need to check the ingame options to know what key is target lock.
