Level 65 to 75. There is flexibility in this guide so tweak it how you need to fit your situation.
Zones: The Barren Coast; The Buried Sea
Quests: PoK: A SImple Task (if appropriate); The Barren Coast:
Steamdrake Potions,
The Abandoned Relics,
Totem of Water and Fire. Each of the quests
Bryden Snow offers is infinitely repeatable and pre-lootable.
Gear: Have Defiant or better. High AC/HP gear/augs are best.
Buffs:
Get the below list of buffs (or more if you prefer):
Righteousness - Cleric level 112 - AC/HP
Talisman of Enduring - Shaman or Druid level 114 HP regeneration
Circle of Igneous Skin - Mage level 111 damage shield
Cloak of the Rimespurs - Ranger level 112 damage shield (stacks with Mage DS)
Voice of Sagacity - Enchanter level 115 mana regeneration
Optional -
Spiritual Insight - Beastlord level 113 adds lots of stuff (stacks with all the above. If it's worth doing it's worth overdoing so stack it if you can.)
SOW,
SOE, or some other flavor of movement speed buff.
Levitation. You don't need either but they make life a lot easier.
Plan:
1. I bound (second bind point) myself in front of
Bryden Snow (loc~ -300,-150) in the Barren Coast to pick up quests and sell to a nearby vendor when my bags were full. Pick up the Hot Zone quest if it applies as this changes periodically.
2. Take the nearby boat to The Buried Sea. Cast
Invisibility and
Levitate on yourself and run due East to the raptor/tiger/goblin/drake island. Bind your self in a safe spot. I bound myself on shore above the tidewater goblins at loc -1370, -3380.
3. First camp, the raptors and basilisks (loc -, -). A named Basilsk,
Dreadclaw (sees invis), is here occasionally. Use your
Staff of Temperate Flux to gather all of the mobs(in
every camp not just this one) around the area that are raptors or basilisks. What! You don't have one! Look it up and go get it unless you have another insta-clicky that can tag all of the mobs and round them up asap. I bound my Tab key and the Staff together so each time I pressed Tab I would change targets and cast Lower Element on that new mob. In this way I spammed Tab to pull all the mobs in the camp into a train. There are roughly 10 mobs in this area. At this point I just let them hit me and cast root on the ones that try to run and then stand next to them. You can cast PB AoE's, Tears, Pillar type, or Beam spells to speed things up but if you have both Igneous Skin and Rimespurs the mobs will take ~ 7k damage each time they hit you and kill themselves.
4. The rest of the camps in the order I exterminated them are:
a. Seatail Drakes (blue color; loc -1130, -2525). These have a lot of HP so you can't let them hit you with out casting some spells to hurry the process along but you can, if you have full appropriate level Defiant gear and the buffs above, gather them all together at one time and blast them while they hit you and die on your DS.
b. Tidewater Goblins in the cave (entrance loc -1025, -2825). You can, with levitate and a run speed buff, run into the cave, gather all of the goblins here in a train and make it back out of the cave before the entrance door shuts. On multiple occasions I would be stunned twice and make it out of the door Indiana Jones style. You will need to help the burn process with these mobs too as they hit too hard and have too many hp for you to not burn them down along with your DS.
c. Tidewater Goblins on shore and along the bridge (loc -1340, -3345) including the two inside the tower at the water's edge but not in the water as that will slow you down considerably. After killing the five at this camp cast invisibility and swim into the water to see if the named goblin,
Maleko, is underwater. Kill none of these as each is a potential placeholder for him and having to swim down here each rotation will slow down the xp. I found him only once in the water but all other times he was one of the five above the water either on the shore, the wanderer on the bridge or the two in the tower at the water's edge.
d. Ashwing Drakes (red color, see invis; loc -665, -3320). Only five mobs in this camp and occasionally a named. They have lots of hp and cast spells so burn these down also while they hit you.
e. A second camp of Raptors and Basilisks. (loc -185, -4125) Another easy camp. A named Raptor,
Helushka is here occasionally. Repeat what you did in #3 above.
f. Sunstone Goblins. There are several camps of these red goblins. A cave entrance (these see invis, loc -150, -3790) is similar to the Tidewater Goblin cave so the same strategy is used here as there but it is easier to run in and get out of. A second camp (loc 200, -3450) avoid this as the Sunstone High Priest (non-named and always up) will debuff you. If you don't care about that then by all means its another eight (8) xp mobs. A third camp is at loc 285, -2870. This is a larger outside area where the goblins are spread out in small stone shelters, standing outside, and one that wanders into and out of this camp.
Lutzan, a named Sunstone Goblin, is in this camp and from what I experienced he was only in this camp and was significantly rarer, about one spawn for every three times Maleko spawned but that may just have been the RNG. There is a fourth camp at loc -25, -2620 (see invis). It is a cave with no door and holds about six goblins.
You can do this in any order you wish but I did the Raptors and Basilisks first as from time to time I would get someone showing up for the kill quest and they would take my kills away. By the time you clear all of the camps the first camp will have re-spawned so that you will not have a break in your xp grind. In essence you are making a counter clockwise circle around the island.
5. Not all of the camps are equally easy. The Raptors and Basilisks, Goblins (either red or blue), red drakes, finally the blue drakes in that order are from easy to hardest. I suggest you use your AoE's like Tears and Beams once you get them to help you. If you do not have these spells just don't pull all of the mobs in a particular camp at once if you are not comfortable or capable of doing so.
6. Gate to your second bind point, i.e. Bryden Snow in #1 above when your bags are full or all of the quests are done. Vendor items etc. Pop Lesson of the Devoted prior to turning in your quests, gate back, start the cycle all over again.
I found myself filling my bags up close to the time my secondary gate refreshed. I tried the other islands in the zone but none could match the sheer number of mobs so close and so easy to kill. I went from 65 to 75 here
AND ground out 1000, yes one-thousand, AA's (100% into AA xp after I got level 75) in about a week and got at least 30kpp in vendor items.
I hope this helps.
