Artists should go water/ice in 1st job because they get additives to only water/ice in 2nd. They also get 2 new attacks.
One is an AoE attack that hits 6 monsters up to 15 times. I think it's AoE range is increases as the skill levels up. Master Lv5, can add sp @Lv60/70/80/90/100
It's damage is apparently based off water element, so all water element buffs apply.
The 2nd attack, not sure exactly, translators suck, but it's a poison type draining skill.
They also have heal skills, attack/def buffs and attack/def monster de-buffs.
To add, they have what appears to be a skill akin to MapleStory's hyper body. Increases max HP

HP-level rise each lasting up to 70 hours, 10 minutes + Lv × 10 seconds expected.

There was also a sarcastic-ish remark on the lataleJP wiki saying something like "To those who said solo-artists are impossible, I lol@U"
@The poster above, I'm gonna be an artist also.
