To start of your power leveling of orc fighter requires t
kind of a lot of money to start with, what you need is Weapon (Attack power):
• Buzdygan (or equal blunt/sword)
• Composition Bow
• Start with 2000 no grade soulshots (NG SS)
• Start with 1000 Wooden arrows
Armor (Protection):
• Bronze Breastplate and Gaiters
• 'Bracers'
• 'Boots'
• Hard Leather Helmet
Jewelry (Magical Protection):
• 2 Coral Earrings
• 1 Blue Diamond Necklace
• 2 Blue Coral Rings

When you first start your new orc fighter you start just outside the "main town", if you like, do the first starter quest to get 50 free skill points and an Elmore map (map over orc village and dwarves village and surroundings)

Head straight out of north gate of orc village, and walk all the way out to "waterfall" (loooong walk, and over an bridge) when you have passed that bridge just keep walking straight up there, now for the next hour and half you will kite the 'Evil Eye Patroller', at this point they are dark red to you since they are around level 13.

Use soul shots for each shot with the comp bow till you get close to level 7, at this point you have collected enough skill points to go back to town and max out all the orc fighter skills, head straight back to that spot, and do the eye's until you are around level 9, then you can alternate kiting the eyes with the bow, and crack some 'Grey stone Golem’s head with the buzdygan and soul shots, if you get low on HP, go back to kite the eye's until you run out of
manna, by then you should have regained all your hp back.

Levels 10-20
Wow level 10! New skills! Finally! Okay, in general this how your skill selection should go: Weapon Mastery, overhit skill, armor masteries. Killing fast will keep you from taking damage, and gain you levels and cash faster.If you don't already have your 14k (i.e. 14,000 adena) weapon, buy it. Iron gloves, for example, sell for about 9k used.
Here is the exception that I was going to mention about money. You need a wooden set of armor. Wooden gaiters are not available for sale in Elmore so you will have to buy them from someone. This has become quite the racket for people to sell these. I've seen them go for 14k. In general you should be able to buy them for less than 10k ideally somewhere around 9k (they sell for 6k in the stores so you will need to sell these in Elmore when you are done). It would be best if you could find the helmet and breast plate used as well (remember what I said about renting for free?). This set gives you additional HP and 2 extra PDef, making it superior to bone or anything else. You will be wearing it until level 20 so get used to the look of it.
You are still killing green and light blue mobs, so starting with kasha timber wolves and mountain fungi, then moving on to maraku werewolves. Really don't move onto the werewolves until you can kill them really fast. There are a couple reason for this beyond the general reasons for killing fast. One is that there is fierce competition for them, you can drive it off literally by killing them frustatingly fast. Two, you want the werewolf totems (worth 600 adena apiece, note you seem to get more of these the first time you complete the quest, so maybe follow my below advice for awhile before completing it the first time), but I was averaging 17-20 for every 400 or so killed. Three, this is the first mob you are killing that has a chance to drop a nicely priced item, namely Iron Gloves. You can get one of these every 400-500 kills (I usually sell these for 9.5k). Remember as far as the totems go, you need to be on the quest to get them, so every time you hear the *ding* sound that means you have 40 in your inventory, throw out about 20 and kill some more. How long can you do this? I did it until I was level 19, at least 50% of my experience each level was in killing werewolves (which is alot of killing when you get .06% of your level on each kill). As they get boring and you get tougher, go spend time killing darkwing bats and grizzlies. Don't go back to town until you have both quest rewards, it isn't worth the walk back out. Note: the bats can drop a Dwarven Mace, but rarely. I got one after about 1000 kills, and sold it for 52k.
Now repeat after me, I will not go to the mainland and waste money coming back until all of the following: I own my 150k weapon, I have a gatekeeper charm (kill the greystone golems for this quest), and I have enough loot that with the sale of my 150k weapon I can buy my 250k weapon. If you go to get a pet, just see what it's like, or for any other reason, you are wasting money and will enevitably come back. Ideally you will want to stay in Elmore until you hit level 19 and can do your changing profession quest.
There are several things you should not do on your way to level 20. Don't go kill Kasha Bears until you are level 18 or so. I know it's tempting, but it's dangerous and slow, and really you can make more elsewhere. Don't do the Merciless Punishment quest right away. The guy you have to kill is over by the Cave of Trials, you have to kill him and head back to town three times, and there is always a line. The one exception might be if you are gonna use the sword, but in that case, buy the stupid thing used, as many people are selling it. It sells for up to 14k, but I see it for 11k all the time too. Do this quest at a higher level, waltz over after killing bats (since it is not too far), when you are ready to go back to town anyway, and see if you can kill him in fifteen minutes or so. He spawns every five minutes so in other words short lines.
At level 19 you will want to start your quest to change professions, you've certainly waited long enough. Go ahead and do the part that's in Elmore. After that, here is a warning, it is hard at your level to do well on the mainland without a party, so it would be best if you went ahead and got about 75% of your level before leaving. That way, when you finish your mission on the mainland, you will be about ready to level and can easily do so. Also, if you don't have enough money for your 250k weapon (haven't you been following this guide?) make sure you can get it when you go, if that means selling your 150k weapon before Gludio, so you should have no trouble getting some.
Another potential hunting spot might be for Lireins and Lirein Ribes up near the bridge west of the Elven Fortress. Get the Catch the Wind quest (Elven Fortress) so you can collect on the Wind Shards that they drop (30 adena apeice, but they don't always drop). Since all the mobs in this area are agressive it might be dangerous before you have both decent armor and weapons. As well, this area tends to be overun with people, particularly bowmen, so expect a lot of KSing and competition for the mobs.
Well, this is some very general advice, I am currently level 24, I will update this as needed, but by now, if you've followed this guide and are laughing at the level 20s that are still using a 65k weapon, bone armor, and soul shots on every battle (again shame on you if you use these ever, except to avoid death!), you probably can chart your own, wise path.
