Don't forget the flightpath and restock and fish.
Turn it in and get two Bloodbelly Fish from the NPC on the docks.
You get the meat from "Giant Softshell Clam", which are openable objects on the ocean floor.
And don't die because it SUCKS getting back. Just play it really, really safe.
Click the book at this location to get the quest.
Weaken the monsters and then use the gem in your inventory on them when they're almost dead. It ticks for 100 damage at slow intervals, sso they need to be really low for it to do it's magic.
The seer is at the top of this tower, kill her and loot it.
Go in this big building. Go in the center. Clickify the crystal. A level 37 demon pops out, he's a tough fight but definitely do-able.
After this, grind back to the guy you got "Sceptre of Light" from and turn it in, get the follow up "Book of the Ancients".
The Drysnaps around this area drop the silver key.
All the guys you need spawn around here. The Slitherblade Naga should drop the Rackmore's Golden Key while you're doing this, if not keep grinding until it drops.
I find it best to hunt around this island so that you can come back to eat/drink when you get low.
The item you need drops from the Oracles in the water around this area.(I actually find it easier to get on the main island where steps 13 and 14 are, but your mileage may vary.)
Here, stashed behind a tree, is Rackmore's treasure chest. Right-click it to end the quest.
Click the statue and fight Lord Kragaru. He's level 38 and a TOTAL DICKWAD. Took me three tries before I finally got him. The trick is to do a big heal way early. If you're a warrior the trick is to die a lot and then give up.
After you're done, turn it in. Turn it in. Don't forget. Everyone forgets.
