DFO: Elementalist

-Sunburst and Fire Pillar to 1. You aren't Light or Fire, so you have no pre-requisite on it for anything else.
-Max Mana Shield or don't get it at all. Anything below 5 is completely worthless.
-Final-tier skills, level(dungeon fighter gold) 1, max, or don't get it at all.
-Drop Pluto to 10 to keep Frost at max.
-Max Mobile Cast. Max Magic Festival. Max Elemental Burn.

Battle Mage

-Drop Punto Wave to 1. Damage scales terribly.
-Max Mana Shield.
-Phase Shift. Level 1 or max. Post-warp gets you sometimes if you misaim. Recommend max.
-Recommend only having three Chasers max, not counting Neutral. We would drop Shadow. Stabbing Wheel tends to be a combo-ender after a line of OTGs.
-Recommend maxing Golden Dragon Spear. Chaser damage scales roughly 90 damage per level. Considering seven Chasers (seven hits), that's 630 extra damage per level. Explosion scales nicely at roughly 200 per level. Stabbing speed also helps to combo easier in the case you miss.
Extra points, etc. Do whatever.
-If you want Awakening, Full Swing level(DFO powerleveling) 5.
