If you are a warlock does having a higher dex = a better chance at hitting stuff with your spells.
Code:
Reflex: is used against abilities where speed and coordination might allow you to escape the brunt of the attack. Examples of spells of this type include acid blast, call lightning, fireball, hellfire and magma spray.
I am just wondering because 3 of the spells listed are warlock only. Also I *think* I read somewhere if you do have a high dex your can avoid spell that can be resisted to reflex.
