Myrna : Attack or Magic ?

[Akatosh]

Hello

I just got Myrna in my team, and I'm wondering what stats I should increase with my cristals ?

Her daggers skills are linked to "Attack" and have no cast time, but all her pieces of armor are giving Magic and reduced casting time.

I'm a bit confused :|

I have problems to see easy, if an attack is a spell or skill. For example i imagine that Daryon's first "two in a row Attack", which is doing lightning damage is a skill and is improved by the Attack skill, is this even right? Because the description is telling something about physical attacks.

Any advice to see the difference? Edit: Ahhh, i see it on the skilldescription (primary stat).
