I started as CNJ thinking all classes I subsequently play will have a heal skill available to use. Reached level 10 and swapped class only to hunt in vain for a way to equip a heal skill.

1. Is there a level requirement for the secondary class before it can equip skills from previous classes? (if not, where do I find these skills to equip them?)

2. Why does the AOE heal sometimes heal those nearby and sometimes not? (seemed to work on anyone attacking same target, but didn't work when I just random healed an area I ran through)

3. Also can anyone tell me at what level CNJ gets Raise skill?

Thanks
