Do you think is a good build or i must change some feats/arcanas? I also have 11378 golds left, what can i buy?
In the group we are: a druid, a sorcerer( areally good-one), a 2 weapons fighter and another guy( he hasn't yet decided).

Okay. First off, the magus is a melee combatant. That means that your primary ability score should be Str, not Int, since that governs all your attacks and damage (or, with the right feats, use Dex instead of Str). You should also invest in a belt of strength +4, by this level. Intelligence is good to have, but not your first priority.

Since you're not fighting unarmed, I don't think you'll get much benefit from dragon style; that also means you don't need the style fusion, and can go straight Magus/10. Magus is a more powerful class than Magus + Monk. Or if you're going to cast a lot of shocking grasps, a one-level dip in crossblooded sorcerer is a good choice.

I suggest you prep some defensive spells in addition to Shield, such as Mirror Image and Displacement. It's not a bad plan to carry a wand of Shield so you can just cast that every combat, as well as a wand of True Strike. You have wand wielder selected, and it's a nice arcana, but only if you carry a bunch of wands around :)

Note that the Magus's greatest strength is Spell Combat, which you should be using as often as possible. However, that does give you a -2 to hit. Power Attack is therefore not a good pick on a Magus, and Crane Style is questionable, as you end up with too many penalties. Note that Arcane Accuracy is an emergency move only, simply because you don't have enough pool points to do it all the time (and because spending a point each combat to give +2/+2 to your staff is a good move). In fact, Hasted Assault is probably a better pick than Arc Acc.

Finally, in terms of feats, Cleave / Cleaving Finish strike me as too situational to spend feats on; and note that Intensify Spell is more effective than Empower.

+1 to Kurald.

If you are going to dip Master of many styles for the free feats, why dragon? Its major benefit is from fighting unarmed. Crane is nice to get your AC to really high levels, but the trade off means your attacks are going to have major penalties from spell combat. If you are going to dip, Kirin style is hands down your best choice. Bonuses to monsters you identify, and with kirin strike you can add your intelligence modx2 to damage as a swift action. Monkey is decent for swift action stand up and never provoking when you stand up. Snake is also good but you would need some ranks in sense motive.

You have a ton of cash. Buy wands, lots of wands. Anything that does not have a DC or won't be metamagic can be on a wand. If it rarely comes up, put it on a scroll. Boosting your strength and intelligence is important, so buy the relevant items as you can afford. A quick runners shirt is cheap and incredibly useful, as are eyes of the eagle. Gloves of storing are expensive, but if your going to use a lot of wands its useful.
