Chaincast Lightningbolt actually works pretty well, as far as mana efficiency. The only downside is half as much distance.
As for enchants...
Mana Reduction is a must have. Get that somehow, common way is Mana Magician.
Accessories: Sweet Pea
Hat: Solid(or Curing)/Wisp
Clothing: Wisp
Gloves: Wisp
Shoes: Mana
Shield: Solid/Wisp
Weapon: Formal
It's not possible to use all of the above and still have Mana Reduction, you have to sacrifice at least two: Hat (Leather Hat-->BBFH) and Shoes (?-->Magic School).
So the best possible Mana Set is +94MP. Unless you go for higher rank enchants like Mana Wizard (1-3 Mana Reduction, +20 MP) or Wizard (+40MP).

My advice... don't go rafting?
it yields nothing of value that anyone needs.
if you're going for the money, then try farming, merchanting, or shadowmissions.
Craploads of herbs, threads, braids, tough strings, and iron ingots. You can easily make over 50k in one trip: farming is
way too slow, merchanting is a hassle (and i don't like exploiting trades kthx), and shadow missions aren't too great unless you find a super rare item.
