Warriors are the strongest melee attackers in the game in terms of raw damage.
Warriors have a huge amount of HP; up to twice as much as the other classes, and Spearmen even more so with their skill “Hyper Body”.
Warriors have the strongest armors in the game in terms of defense. For example, the level 60 Warrior helm has twice as much defense as the level 60 Magician helm. Fighters and Pages also receive the skill “Power Guard”, which nullifies 40% of the damage they receive and reflects it back to the enemy.
Because of their high damage, HP, and DEF, Warriors can hunt some higher level monsters more easily.
Warriors are able to “tank” most monsters.
Having high “Str”, Warriors are ideal for first time players to get through the game.
Warriors can easily take down monsters faster than any other class, which makes them perfect for parties with Thieves or Magicians.
Cons:

Other classes such as Bowmen and Assassins attack long-ranged, meaning that they would be able to kill monsters more quickly than Warriors. This can also lead to Warriors being KSed often. To make matters worse, Warriors are also the slowest class in the game in terms of speed.
Despite their high HP and defense, accuracy remains the downfall of every Warrior. However, Warriors often compensate through the use of “Sniper Potions/Pills” and equipment scrolled with DEX-scrolls.
Because Warriors have to get up close to the monsters to kill them, they usually end up being hit more often. Therefore, they spend more Mesos on potions.
Warriors can wear equipment such as the Jousting Helm that hides the entire head. Even though these helms are high in defense, any NX Cash that was spent to improve facial appearances are sacrificed to some degree unless more NX Cash is used to cloak the helm.
Because Warriors are melee characters and get hit often, low-leveled Warriors spend a lot on HP potions. However, they make up for it later in the game as their defence grows.

I’d have to disagree with this one. Sins have to spend money on stars and MP potions as Lucky7s is their only way to really keep up with everyone in terms of damage. Additionally, Mages have to buy MP potions and Archers need arrows, MP potions, and HP potions. Warriors have the cheapest attacks in the game and best armor, so they don’t need as many HP potions. –Dragontamer
Just to add, IMO the skill “Recovering HP increase” makes my warrior pretty cheap, as it means i hardly ever use Potions. – Morris
I should add that Recovering HP increase is a good skill, but the other warrior skills are MUCH better than it; all warriors will use Power Strike and Slash Blast till 2rd job, and Crusaders and White Knights will use them till 3th job. Because of this, there usually isn’t enough points to max out Recovreing HP increase. –Dragontamer 19:41, 23 December 2005 (UTC)
~Just like to add that warrior is the cheapest job from level 10 to 30 IF you do NOT use blue pots, keep your armour at its best and most importantly STAY at what’s the biggest thing you can fight that only does 1 HP damage. It sounds bad, but compared to getting a mage through the first few levels… or a thief of bowman… on these levels the meso and drops you get are FAR TOO LOW to keep thieves and bowmen funded properly. If you use L7, or Double Shot etc… you will likely go broke before level 30 and you really need the funding to reach the 1 hit killing boars stage where things get easier.
Oh, and yeah the whole HP regen skill isn’t that useful. Most of the time you won’t stay still. I’m maxing it tho purely for hate of Final Attack and because it will help with my lagging and in places like El Nath where the cold constantly hurts you, such that I can go afk on any ropes etc and heal 60 HP every 10 seconds, 360 a minute, and by all rights if you can stand to wait a few minutes yeah it can heal you totally pretty fast.
