The Pure HP Build

This build is not recommended for those just starting the game. That said, it is a viable build for advanced players with money to burn and plenty of spare time. The general premise is this: Once you've got Improved HP Increase to level 10, put all your AP into the HP option, to give your character a monstrous amount of hit points. The advantages of this are that you can go to areas with extremely tough monsters, and not be killed thanks to how long it takes them to kill you. This is probably the build that will let you kill the Jr. Balrog and other powerful monsters the soonest; however it is not cheap to do, nor easy. It is just possible earlier. So you want to do this? There are some things you need to have. First, you need lots of money. Without money, training is incredibly slow, and even once you've got it to a higher level, you won't be able to afford pots. Second, if you want to get any use out of the character, you need at least one friend who is a Cleric. They will probably be more than happy to help heal you, since they get exp based on how much they heal, and you will have a lot of HP to heal. Third, if you want to do this quickly, you will need someone who can enter a party with you and train you.

Once you have these, you are ready to begin. The ideal stat build is as follows: Roll 12 STR, and 4 in 2 of the other stats, 5 in the third. Since you do not need damage, it doesn't really matter where the 5 is. Eleven or 10 STR is also permissible, but you lose 50-100 hp.

From level 1-6, add points into STR. Stop doing this when you hit 35 STR, as this is all you need to do the Warrior job advance. This should happen at level 6, and you will have 2 spare AP. After this level, keep storing your AP, because you will get the most benefit from it after you have the HP Increase skill at it's maximum level.

To train, you will probably want to stay on Maple Island until level 6 or 10, depending on whether you have the friend to party with and train for you. Up to level 6, it is faster to train on your own, but at level 6 you get a reasonable amount of experience when in a party with someone, and the amount of exp you need to level up jumps dramatically. If you cannot find someone to do this, just stay at Maple Island until level 10 - snails are your best option due to only having 35 STR, and there are no better equipments on Victoria Island.

Once you hit level 10, you are ready to become a Warrior. Once you do this, you have a multitude of options - you can keep having the person train for you, or you can go to Ossyria, and use the Item Exchange Quest to gain experience. This is a simple quest where you return 100 items to an NPC, and he gives you 500 exp and some randomly chosen prize. Thus it is very fast to train in this way if you have the items readily available - and if you have the money, you should be able to buy them from other players. Now that you are level 10 and gaining, we turn to the SP Build.

* 10 - 1 Improved HP Recovery
* 11 - 4 Improved HP Recovery
* 12 - 5 Improved HP Recovery, 2 Improved HP Increase.
* 13 - 5 Improved HP Recovery, 5 Improved HP Increase.
* 14 - 5 Improved HP Recovery, 8 Improved HP Increase.
* 15 - 5 Improved HP Recovery, 10 Improved HP Increase.

Thus at level 15, you have the skill Improved HP Increase at it's maximum level, and you have all those AP that you saved up since level 6 (47 if you get ideal stats). You can just put them all in the HP option and watch your HP grow to an enormous number - at the end, you should have around 3,000HP!

After this, the SP usage is not very important since most of the 1st job skills are pretty much useless. If you want to try fighting for yourself, you will be weak, but you can get the damage increase skills first. If you just want to use the Exchange Quest more, or leech experience from someone, maximize Improved HP Recovery and Endure, as they are more useful to you. The AP usage is simple - put all the points in HP every time you level up.

The Exchange Quest remains a reasonable way to gain experience until level 21, at which point if you can find people to enter the Party Quest with, this will be a much better way to get experience. At level 20, it costs approximately 100,000 mesos to level up using the Exchange Quest if you trade Solid Horns, which can generally be purchased for 50 mesos. So if you're poor, this may not be the best thing any more. The reason for the variance in price is that the prizes you get have different values - some are worth almost as much as the money the items cost, some are worth less than half. As for the Party Quest, you won't do any killing, but if you can find a willing party then go for it!

Level 30 is the next interesting point. You've got here in whatever way, probably costing vast amounts of mesos, or taking a ridiculously long time, but you've done it. Now, all that's left before you and your ultimate success is the 2nd job advance test. If you're in MapleSEA, the test is impossible for you to complete by yourself (and by impossible, I mean impossible. Not a chance. Zero). You will need another regular warrior who's completing the quest to help you: Let him kill the monsters, and you can then loot their marbles. Now, the chance of finding a warrior who's job advancing at the precise time as you are is... not very probable, so good luck, you will need it. If you're in GMS, though, then you lucked out: with Three Snails, lots of HP/MP potions, and heck of a lot of shells (bring 2k just to be safe), you can actually do this by yourself. Try to pick on Fire Boars, since Lupins will throw bananas at you when you hit them.

Once you have done that, Congratulations! You will now be getting the most useful skill to you: Powerguard. Powerguard is available to both Fighters and Pages, but Fighters are generally considered the better choice thanks to gaining several hundred HP when they choose their 2nd Job. Either way, Powerguard does the same thing - returns some of the damage monsters deal to you by running into you (bump damage) to the monsters. The reason it is so nice is because of how it works - it returns a percentage of the total damage done to you. Thus, the stronger the monster's attack, the more damage it will do to itself if you run into it. This damage ignores accuracy, so if the monster hits you, you hit it back, unless it hits you for 1 damage. In that case, you would not be doing any damage at all, so it records a "MISS". As you can see, with a massive amount of HP, this means you can take on some of the strongest monsters in the game, and as long as you have a Cleric along or a bunch of pots, there's no risk of you even dying. Heck, if you feel bold, party a Cleric and go kill Crimson Balrog. You won't die if the cleric doesn't.

Once you have Power Guard, you can choose Rage (as a Fighter), or other skills - Rage is useful to party members because it improves their weapon attack, and if you are always training with someone they will appreciate this. Rage also decreases your own weapon defense, increasing Power Guard damage ever so slightly. It should be noted that your armor cannot go below 0.

And there you have it. The (nearly) Pure HP Warrior. With an estimated 8,000hp by level 30, and rising to 15,000 at level 50, you are in no danger of dying from any of the monsters currently in the game. Clerics will also love the hundreds of experience they get when they heal you.

(addon) However, because of the previous patch, shell throwing can now miss, so this build is nearly obsolete, unless you get some dexterity points, which will cause you to lose a few hundred/thousand hp. The only way you can get a hp pure is with NX cash.

* Note to the addon: It is also possible to do the job advancement without the snail throwing. You will need 40 accuracy to hit the fire boars and lupins, 80% of the times, that's not so bad. But you will have to get some really good DEX and accuracy bonus. Equips such as Pig's Illustrated, Brown Bandana, Accuracy work gloves, and sniper pills will work fine. With all these, you should be able to hit the monsters most of the times, just bring some warrior elixirs (from NLC) to increase your dmg (it may still be painfully low, probably around 100 per power strike). The advancement will probably take you at least an hour, but it is absolutely completable, so HP warriors, don't get your hopes down =D
