Battle mage?

[Vanguard319]

It's possible, put in enough Int for mag. attack, Pie for magic acc. and equip a sword that offers high magic potency (and yes, there are a few with such as hidden stats.) I can't say it would hit like a Con or Thm's spells though, and you wouldn't be able to use AoEs. I used to include Thunder in my action bar as an arc, mostly when in a crab party, I'd get resisted more often, but I could continue to deal some damage when the crab raised it's guard.

On that note, my Archer has somewhat high max MP for a DoW (573 at r50, and 628 with my usual gear) my mag. potecy is 17 (given by my bow) and mag. acc is 117 so my elemental spells won't land as hard or as often, but it sounds like it would be adequate for DoTs/heals/buffs at least.
