1. Dragon's Killer Instinct has a bug in it, where it stays with you when you log out, so if you have lvl 1 and then log off, than back in you'll effectively have twice the bonus of level 1. So the thing to do is to never put points into the skill until you have a high enough level to put all of the points you'll ever put into the skill, do so and then log off, and log back in and respec the points from the skill.
