Critical Strike

Usage Notes
Unlike most skills in the Guild Wars Universe, this skill actually becomes less effective the more points you put into its corresponding attribute (Critical Strikes). This is because of the simple fact that the higher the level of the Critical Strikes attribute, the more chance that you will automatically score a critical hit. It's obviously wasteful to use a skill to make something happen that had a good chance of happening anyway. On the contrary, if you put few or no points into Critical Strikes, this skill is very effective.
