Sry for bad English

Skill two is a sword only skill, you have two swords on, you need only one, if you want to use two sword you have to learn dual weapon skills.
Skill three has to be used on a monster, you need to click on a monster and press three.

You need certain weapons for certain skills otherwise you won't be able to cast it. ;)
