boi gold, Battle of the immortals Gold

Go talk to the Duke of Lumbridge in the second floor of Lumbridge Castle. He’ll give you an anti-dragon breath shield. Smith 12 nails from 6 steel bars (also possible to purchase boi gold off of someone). Go to the cemetery northwest of Varrock in level 18 wilderness and acquire 3 planks.

Withdraw 2k and a hammer and head to Port Sarim. Talk to Klarense at the dock and buy the broken boat for 2k. Talk to Ned in Draynor Village and he’ll agree to sail you to Crandor Isle.

Prepare yourself with all the items needed to kill a high-leveled dragon. Go back to Port Sarim and enter your boat. Fix the broken cracks with your nails and planks. Then talk to Ned inside the boat to sail to Crandor.

Head around the cliffs on Crandor and enter the dungeon on the middle of the island. Head south past the skeletons until you see a big chamber to the west of you. This is where the dragon is.

Head back and talk to Eohric. He’ll tell you to try to get Harold drunk. Head back to the bar. Acquire an Asgarnian Ale from the counter (or buy one from the bartender for 2gps) and head upstairs again.
