Taken from the guide I did a while back:
http://wiki.project1999.com/Druid_Le...#Level_30_-_45
Level 30 - 45
32 - 37 Frontier Mountains: Giant Fortress, root/rotting at first, then quadding when mana permits, probably post 34.
Item Alert Forest Loop - Ear, 2 Armor, 3 Wisdom, 3 Agility, 3 Dexterity. These are somewhat rare but drop off of Mountain Giants throughout the zone if you stay long enough you can fill both ear slots with great druid items.
35 - 38 Upper Guk: Ancient Croc Camp, this camp is a little more dangerous but you can use charm animals.
Item Alert Gatorscale Leggings - Legs, 7 armor, 4 Wisdom, 15 HP.
35 - 42 Firiona Vie: Quadding Drolvargs and Pirates in the cliffs.
36 - 45 The Overthere: Quadding everything near the FM zoneline. The OT is also a great place to charm kill animals.
42 - 45 Emerald Jungle: Can charm kite some of the trakaraptors and gorillas.
Epic Alert - Be sure to check track for a Tainted Gorilla, killing it will spawn a Corrupted Gorilla and allow you to loot Green Tree Bark, this guy will be hard to kill at this level so you may need to get a few animals to charm and help beat it up.
40 - 45 Rathe Mountains: Killing hill giants, generally root rotting, possibly quadding if mana permits.
Epic Alert - Be sure to check track for Tainted Hill Giant, killing it will spawn a Corrupted Hill Giant and will allow you to loot an Ancient Rock for epic.
[edit] Level 45 - 55
43 – 46 Butcherblock: Camped the dwarves in BB. I put this in because it is a definite option however, be weary there are faction hits. Note: the faction hit will not interfere with your ability to do the portion of the epic quest in Kaladim.
46 - 51 Lake of Ill Omen: Quadding Bloodgills
Epic Alert - Check track for tainted Deepwater Barracuda to spawn the Corrupted Deepwater Barracuda to receive Pure Lakewater
47 - 54 Dreadlands: Quadding everything outside the North or East wall of Karnor's Castle.
49 - 53 Timorous Deep: Quadding Aviaks, great XP not great loot
49 - 54 Ocean of Tears: Quadding or Root/rotting seafuries. This is great plat but not the best XP available.
Epic Alert - Be sure to keep your eye out for a Tainted Seafury, this will be hard for you to solo but the other people camping the island will prefer to have the Tainted Seafury out of the way and they may help you kill it, it will spawn the Corrupted Seafury and you’ll have another piece towards your epic
49 - 54 City of Mist: Root Rotting
