Wizard/Bard Guide!!!

Warning: Big wall of text under the page break

If you want to be a bard I suggest you be a healing wizard (so you can train yourself to keep an eye on your sp). Healing wizards suck when it comes to healing (compared to bards) but if you intend to do coliseum at level 15 you it will be really helpful to your party members. http://youtu.be/v1ZKkG-kn4g (that is the level 1-50 healing wizard season 2 build-in level order). A more offensive wizard build would be taking 3 or so elements and maxing their skills completely.

As for bards there are three different types of skill builds (these are just general guidelines). There is Pure Support, Attack only or a Hybrid build.

When building support put priority on upgrading buffs and heals and work your way down the mind square tree maxing purification as soon as you can. The Ice Storm skill is somewhat helpful because it will freeze the enemies in place for a few seconds (reduces how many times you have to heal) and its always fun to attack when you can.  

If you are going full support remember to keep an eye on your sp- if you run out of sp then you can't heal. And when you can't heal- your party members die. Don't expect your party members to keep an eye on your sp either, its not their job to do so. Do expect that most party members are idiots and will jump into that mob when your sp is low and occasionally you will be yelled at when you let someone die.

When building Attack put priority on upgrading your water skills (except bubble bubble that skill is pretty useless compared to the others-max it last), also make sure to max Elemental Protection and Elemental rage (under misc skills) as soon as possible because they give you attack crit rate + critical damage. Also the Electric shock guitar skill is probably the only useful guitar skill (you can't get it at level 50), you will probably want to put a few points in that skill too.
Evil performance is useless don't bother with it.

When building Hybrid make sure to put at least 1 point in guitar performance party heal skill. And put the rest of the points into the skills you want. I honestly think hybrid builds should have two buffs to buff themselves/party members so pick two buffs that you like and put the rest of your skill points in your water skills.

Since you are going to be a bard I'm going to give you a rundown of your buffs:

Power Recital-Max damage is always helpful, this is one of the 'mandatory' buffs (mandatory= only if you are going support/hybrid).

Sacred Performance-This is that other mandatory buff :). More damage= faster kills= more xp (and it gives you a defense buff too!).

Unity Performance-accuracy is helpful if you guys wanted to kill red/orange named monsters. This is a situational buff- would probably be helpful to get at around level 75 or so if you are going to do spooky 90.

Sound of Water Elemental-seeing as only bards and sorcerers use water attacks this buff is useless for a hybrid/support bard (nobody wants to stand there for longer than they need to when you are buffing). Even as an attack bard your 3rd mastery gives you free intensity + max damage (unlike this buff)...so it really is pretty useless. Never get this buff. Ever.

Sound Wave Protection-This is totally useless as a bard (it is slightly better as a minstrel), -10 damage is nothing at your level (and it gets only more useless as you level up =.=). Plus it only lasts 5 minutes.

Elemental Shout-Could be helpful if it lasted longer, as it is...11 seconds of enemy reduced defense is pretty useless.

Sound of Heart-A lot of people would tell you that the +stat buffs are useless but from my point of view more stats=easier time killing things. Even if it was just +20 stamina it would still help you survive for longer. This should be maxed regardless of build because its free stats.

Sound of Holiness-This is probably the other buff you should always have regardless of build. Ever wonder why knights don't get knocked back as much? Its because their hp is so high. The more hp you have the less of a chance you have at being knocked back/flinched from enemies attacks.

Hearing Confusion-Just like elemental shout this would be so much better if it lasted longer/if you could get it at a lower level. As it is at level 85 it is somewhat useless. If you are going to go bossing (like time attack instance dungeons invoke/hyunmu) then this might have some use. I would put an extra skill point in it if you have a free skill point.
