Basically you will want to use AOE (bowling bash) to clear groups of enemies at once. "Single target leveling" is somewhat okay up to level ~80 but gets really slow afterwards and isn't an option. Eden leveling quests (not gramps) is decent up to ~80 as well. You might be able to stack those with the bounty boards for Juno area.
But after 80 you really need to be able to AOE level if you are going the soloing route. AOE leveling means keeping your HP and SP up using potions or certain gears, which can get very expensive. For HP some options are Witch Hat + Alarm Mask combo with pumpkins, Fresh Fish (not effective at high levels), Ice Creams with Snowier Cards, Aloe Leaflets (cannot be bought from NPC, only farmed or bought from players), or just using regular potions / slim potions (gets very expensive). For SP some options are natural regen (knights have very low SP pools), Vanargand Helm / Rideword Hat, and Earth Deleter Armor. Note that you can't use Vanargand + Witch Hat at the same time obviously because they are both upper slots. The only way to use "both" is to swap between the two mid-battle, and not many players are able to get their timing off well enough.
Probably the most "doable" option is to use Witch Hat + Alarm Mask + Earth Deleter Armor. This only works for melee characters like Knights though. Also note Bowling Bash takes quite a bit of practice due to the gutter lines.
So soloing does get quite tough and/or expensive. That's why most players, even veterans, just do Gramps Turn Ins.
Note: I'm a returning player, and a vet in RO(I have been playing since RO went live, infact I remember having to wait a few days for the game to go live). Also aside from the boat load of equips I have, I'm also sitting on 300m atm(I'm saving up for a Asprika atm for my Rogue char, and all my char if I decide to do WOE again)
For SP I have a Earth Deleter armor, and the spear that regens 1 SP per hit. As soon as a damn Ulle's Cap comes on the market, Ill be buying that for the set bonus as well. In short, SP Isn't a Issue.
I'm in the middle of leveling a AOE skill now(Brandish Spear), so yea I'll be fine(by the time I hit lv 80 it will be lv 10, and I'll most likely have Lv 5 Spear Dynamo when I hit lv 80 as well).
How about Prize Medals, is that a viable option, how many base/job levels can I get with 750 medals(after all 40m zenny for 1000 medals Isn't much, so I was thinking what the hell, might as well use them for xp)?
