RP at this lvl has a lot of options to hunt, so I'll mention some and describe why.
*Ghastly Dragons cave: that's a hunt full of profit. I recommend you hunt with crossbow and fire walls and bombs.
*Undead Dragons WOTE: this place is very good too for paladins to make a good money. Here you can also have a chance to find the boss Hatebreeder and some chance to drop the Shield of Corruption ( I dropped it twice in 6months). You can also make Bestiary of Undead Dragon, Draken Abomination, Ghastly Dragon and Draken Elite. I just recommend to enter in the northwest TP.
*Banuta -4: here u can make good XP but the loot in general isn't that good. Every 3-4 refill you complete a task at Grizzly Adams.
*Glooth Tower: here is one the best places for paladin in my opinion. You can make good XP and high profit also you complete 4 bestiary. Use thunderstorm and diamond arrows, full set with imbuements. I think a def set would be better if u are close to lvl 300.
*Demons Oramond: this place is good to complete demons task and you can make good XP. Profit is variable, but never got waste there. If u have bad connection I do not recommend to go here, Grim reapers can kill you easily.
There are a lot of other options, but I think with this spots you can have fun during a good time.
