For a Master Sorcerer 80+ with money to waste, i suggest hunting Frost Dragons, in Okolnir or any other frost dragons. Using mainly Exevo Gran Vis Lux, Exevo Vis Hur, Exori Max Vis, Exori Gran Vis, Exori Vis. In that specific order. You will kill them really quickly since they are weak to energy. Take Plenty of Strong or Great Mana potions, Take atleast 150 sudden deaths incase you get into trouble with pkers, or too many Frost Dragons. (You can also take Thunderstorm runes but i don't suggest them unless you have a blocker.)
For a paladin lv 70+ depending on waste. If you don't mind the waste, you can hunt in Darashia Dragons Lords. Take 200 mana/strong mana potions. And take Enchanted Spears or a good bow/crossbow. (I suggest Enchanted Spears + Exori San. P.S Exori San takes less mana than Exori Con.) If your lucky you'll profit with a Dragon Scail Male or a Royal Helmet, Tower Shield. (Usually you'll come out empty handed) But if you loot gps you will make around 1-2k. Your max waste hunting here solo is only about 13k for 200 strong mana potions and ~k depending on how many Enchanted Spears you take.
For a paladin lv 70+. If you don't want to waste, i suggest hunting Ankrahmun dragon lairs 1-2-3. Clear them simultaneously (one after the other). This is great exp, and depending on your skills and if you want to clear all the dragon lords you might only waste 10k for mana potions. You will usually come out with a profit if you make a loot bag for Steel Shields etc.
For a paladin lv 50+. If you want to make almost 0 waste and 100% profit. I suggest you hunt the tomb under Ankrahmuns first dragon lair. It is Great exp, and you loot Health Potions like crazy from Ghoulish Hyaenas. You get GREAT amount of gps. 1 hunt of maybe 15-20 minutes you'll make about 5k+ if you loot all the gps. (Also you have a chance of looting a Fist on a stick for the Dromedary Mount. Worth 60k+ depending on your world.)
For a Druid lv 50+. If you aren't worried about wasting. I highly suggest hunting in Darashia Dragon Lords, take about 150-200 strong mana potions and plenty of Sudden Death Runes. You will make about 200k exp/hr. It will be a major waste unless you're lucky and loot something good.
