Proceed past the quarry into the Limestone Forest ( 460, 138, 58 ) Copy/waypoint 459.89, 137.95, 57.90. Kill all the groups with needlite bloodroyals to spawn The Needlite Queen ( 694, 180, 283 ) Copy/waypoint 694, 180, 283.
Find two slain Defenders of the Haven at ( 390, 139, 429 ) Copy/waypoint 390, 139, 429.
Move into The Chlorochamber and kill all the tegi boglings, including the bogling of Broglyn that pops after each group of three dies to spawn Chief Broglyn ( -42, 174, 379 ) Copy/waypoint -41.97, 173.86, 378.68. Kill him.
Summons a corrupted bogling four times, so 80%, 60%, 40%, and 20%, which curses you with an incurable massive Crit Bonus and Crit Chance debuff. You must kill the corrupted bogling to remove it, or you will die (which also removes it). Duo this if you are low DPS, or bring a merc that will rez you. If you get rezzed, you can kill the add and continue the fight.
If you are having trouble with Broglyn, go back and find the boglings that you failed to kill earlier and kill them. He heals more for every bogling of Broglyn that you didn't kill.
Go to Tuatara Rim ( -171, 218, 133 ) Copy/waypoint -170.95, 217.75, 133.01 and kill tuatara cliffcoasters and tuatara preycullers, then slay Killmodo. This is a DPS check as adds spawn quite frequently. Just concentrate on Killmodo and burn him down.
Find the rest of the Defenders of the Haven at ( -388, 217, -35 ) Copy/waypoint -388, 217, -35 and speak to Hrewa Medinal.
To finish the zone, go to The Colossal Cascades ( -393, 176, 326 ) Copy/waypoint -393.40, 176.07, 325.71 and kill Scyphodon.
Collect colossal cane and use it to be able to see Scyphodon.
When Scyphodon emotes, "Those with a bit of sugar in their veins may soon be devoured!" use /cancel_maintained Magic Sugar. You can also drag the colossal cane onto your hotbar, and use and cancel it by clicking.
Cure elemental dot only while on land. Curing it in the water electrocutes you.
