Meanwhile I'm just sitting here getting chars to level 20 to build up some fame and suiciding them for more fame.
the jump between first hitting level 20, then getting to max a stat is pretty huge
If anything I say you should start getting stat pots from sprite worlds and snake pits before going anywhere else, and try to get a few def pots off of gods if you can.
Once you get spd, dex and def at a high enough stat you can probably brave Oryx's castle and rush just a little bit behind the people in the front, allowing you to make it to the chamber portal before the guardians die, after that just stay with the horde for the oryx battle and keep on shooting him, use your damage abilities if you can, and just be ready to dodge anything he throws.
if all goes well you should get some loot from Oryx which may be some T9-T11 equips which will be very useful for you.
and in the case you do get in a realm where someone opens the wine cellar at the end...
try to rush through it with everyone else, just watch out for the blue confusion boomerangs, they'll be a huge problem for you.
the only other things that will give you problems are the purple slime trails, which inflict slow and sick, and the blue guys with the 20 shot shotgun attack.
Just rush past them all and you should hit O2
If you're either assassin or wizard, just stay back and spellbomb/poison O2 whenever you can, and if O2 gets stunned by a knight, try to get in there and get damage in before he is no longer stunned, and be ready for him to explode as soon as the stun wears off.
you only need around 900 total damage on O2 to qualify for a soulbound item.
and then hopefully you'll get either stat pots or some high tier loot
