Here is a guide to Ursa dungeon.If you own a high level in Rappelz and if you have an alt that's lower then 34,you can go to ursa.
Take as much aggro as you can, let pixie heal you with lvl1 heal, letting her take aggro, then you can kill really fast (1 by 1). Make sure bp has warrior armor. Don't give pixie staff, give it mace or axe. You're a low lvl, you will do crap, but pixie would do alot of dmg. (Thats right, a tank, healer, and a dd in 1). You can do the same thing with angel (If you can get your hands on one. It'd be alot better tank and dd.)
Keep in mind, its a lot easier to make a party when you're a lower lvl. You can also ask your friends to go on their alts.Kill matriarch, and guards. One person go for the Mom. I once made almost 500 gen points doing this strategy, and i only had 4 in party. And it was our first try. We didn't spread out till 13 minutes were left. We could've made alot more. If you can get a party of 8, all with high lvl pets, you might actually make 6000 points.
Here's 7 spots that are good. If you can make 8 people, go for cubs or something.rappelz rupees
