Magic Oboro Skills

So my Oboro right now it's using Flaming Petals, Dragon, Freezing Spear and Snow Flake and no wind spell atm.

I was wondering if I should drop the Spear, since charm doesn't boost the dmg by a lot, it seems it would fall off later on, and use only Snow Flake for water element. And I was thinking I could get a wind spell with the remaining points but I want to know which are the best ones.

Also for Oboro skills, is it me or are most of them not worth getting at all? Like, starting from the fact that some of them are for PVP, but also... Moonlight Fantasy?? It just looks like a massive mess of a skill. If the way the wiki describes how it works is correct then what in the world did I just read... It feels like they mean for you to get more Ninja skills anyways.

From what I understand the masteries only affect your physical attacks, but please correct me if I'm wrong. And I feel like I should mention Makibishi for the posibility of some CC on mobs but... It doesn't seem worth it at all. 

generally you just pick the charms, pure soul, 16th night, distorted crescent, and the rest of the points you lear every other magic skill from the 1st class.

It's also helpfull to have Shadow Warrior. And optionally you can spend the points to lear Shadow Hiding(it's a lot of pre req points) so that you can use it + shadow leap to jump around without having to use some piece of gear that enables Hide, that's if you want to jump around at all.
