Ok, I just found out ( Cuz I am SUCH a observant one =\ ) that you can use Spiked Gloves with the Kamael. Now, the Fallen Sword Skill, you obviously can't use, so my question is, is there any skills that come later on that you can use with the spiked gloves other than the STR increase skill?
You mean "Increse power" self buff?
You can use any weapons you like, but kamales have skills only for rapier, ancient sword or arbalet, depending on your profession. pre-1st profession skills should work with one and two handed swords as well. Not sure about bows.
You might want to check THIS (http://www.lineage2.com/Knowledge/race_kamael_skill.html) and see in skills description with hat weapon you can use it. If skill description does not include weapon requirement, it usually means, that that skill can be used with any weapon.
