Converting Pally to DexMage

[Apolloco]

What kind of weapons should I use? I'm level 7 right now and how should I level up my skills? It's at
2130
0000
0000

at the moment. Should I need more int then just 11 int? Thanks. If anybody could tell me a good build for a dex mage I would appreciate it. I've only started but I wasn't sure if dex helps. I know that Royce stated earlier than dex improves your regular hit dmg and skill dmg. My lightning skill does so little dmg (around 80-100 dmg; same thing as 2 regular hits). Would str be good cause it increases base dmg and gives me hp?
