The best way to get money is to level up and camp Sebilis. You aren't a rogue, clerics don't need gear to be an effective member of a group.

If you're worried about buying spells don't be. Around level 20 is when mobs start dropping fine steel weapons this will be more than enough to take care of spell purchases.

Bull elephants in SK drop tusks that sell for 10pp. I think the normal elephants drop tusks too which are pretty good value.
Also the hermit in SK drops fine steel weapon, but might be a little difficult. (but will be excellent xp if you can take him)
Bone chips, as other have said. There are probably some undead in loio around the right level to get some xp at the same time. I suspect bone chips are slightly oversupplied right now. You would be lucky to get more than 5p per stack in EC.
Carrion spiders in EK for silks might work too, though I would be hesitant to be running around in that zone at level 20 without sow.

I've played casters before, and spell money has always been a problem. Some people manage to be rich and never need to care about this sort of thing, but that person has never been me. It's always been scary when you get to a spell level, and people expect you to have certain spells when you don't. The other people in the groups usually get the loot, and you've spent all your money on gems to buff them with.

A pair of banded pants would be lovely, who can I contact in game?

I've never leveled in the Karanas, can you give more information? :)

You can try killing the bandit sisters in Lfay, their camp is close to Mistmoore entrance. They drop bronze armor which sells decently. Whenever you get a bit higher level you can make decent money in Mistmoore.

And if you're able to find someone who isn't bothered by lowering their faction, the Rivervale guards are good money. They drop spears which are worth 10pp and a shield worth 1pp and some change if you have decent CHA.

I suggest one of you keep your faction up with the halflings so you can sell while the other does the murdering.

That's great, I'm evil so I don't care about halfling faction! What level are the guards?

Stupid halfling faction, what would I ever need it for.

Vellatri.

Ask any lvl 60, most of us are hoarding tens of thousands if not hundreds of thousands (with a few select individuals in the millions) of platinums. Srsly, just ask :P Tis a social game.

I'm having basically the same problem. I have been leveling in Unrest / Oasis / UGUK from about 15 on and I'm at level 21. I have about 23pp to my name.

People actually have been helping me out, too. Heallun gave me some gear and some cash and a couple pp here and there, but I stupidly spent it on like, a robe and stuff thinking I'd get pp as I level.

I don't ever remember being this poor :) If you played progression server, you'd also know how ironic this is considering I was Tomtee there.
