Equipment
The Devotion Set keeps being the best choice for dark wizards until they can get Karmian on c-grade. You CAN however live without it. If you want to, you might prefer to ask a Bounty Hunter around level 35 for Gloves of Knowledge (can be spoiled from Tyrant in Ants Nest, which is the by far easiest way to get them) and buy the rest of the set from the shop.

Weapons are obvious - maximize your m.atk. with the Staff or Life etc.

Playstyle
You should concentrate your skills on the class you want to be come, meaning damage spells for future Spellhowlers and summons for future Phantom Summoners.

With damage spells, business is as usual. You use your largest range spell first to attract the mob, then slow it down with Ice Bolt or Slow, then keep running away and casting damage spells. With Aura Burn, even tight Situations are quite manageable now.

Summoners need crystals, which are quite expensive. OTOH with summons one can face mobs of much higher level in melee.
