The Fairy Rings are along the same line as the charter boat or the ectophial task. All you have to do is teleport in from a fairy ring. I'll even save you having to look it up... the code is ALQ. Most likely, you've already accidentally done this one, especially if you hunt penguins weekly.
Barking up the wrong tree is another one of those where you need to keep for a later task. Go to Canifis, click on the other side of the river, and just run around a bit. The hollow trees are easy to find. (No Keebler elves, though.) Cut some bark, and bank it for later. The next task involved using the western gate of Port Phasmatys. Since we were already close, we just ran over that way. I think we had to be leaving the town for it to count. Don't remember for sure, but it seems like just running into town from the swamp didn't work. We had to use the side gate as we were leaving to make it official. Or maybe it just required a two-way use.
Ready? Trek! found us running through Temple Trekking once again. This is definitely an ongoing theme. From easy to elite, Temple Trekking (and Burg de Rott) are thoroughly woven into the Morytania task set. In this one, we had to take a medium companion through a medium route. Okay,still easy enough. And only one run-through. No big problems, yet.
Back to the simple; our next goal was to trap a swamp lizard. In the Haunted Woods, there's a hunter icon just a little south from the Werewolf Agility Course. Bringing a rope and a small fishing net allowed us to quickly net our quota of swamp lizard. Had to bring an extra net... the one in out toolbelts didn't work.
For Finding Your Balance, we had to make a Guthix Balance potion completely within Morytania. All it took was Harralander, Red Spider's Eggs, and a vial of water to make a Restore Potion. Then we added Garlic and Silver Dust. For this one, the GE was a great way to get all the parts. Then just ecto in, mix the brew, and we're ready to hit the next one.
The Beer Inn-spectre is a follow-on from when we had to come down here for the easier tasks. We did ours at the same time, but if you're coming here from scratch, you'll want to come prepared to make either Ale, or Cider. Cider is simpler, but both are easy enough. For Cider, just bring 16 cooking apples and 4 empty buckets. For ale, it's 2 buckets of water, a couple of barley malts, ale yeast, and whatever main ingredient you choose. I think we used ground chocolate, but don't really remember. This kind of stuff is Monique's specialty, so I just followed her instructions.
Brain Bending is a somewhat creepy telegrab assignment. Get to the Canifis tavern (Hair of the Dog) any way you like. If you've got a house teleport for it, that's easiest. Bring enough runes to telegrab, then use the telegrab spell on the pickled brain. It's on one of the tables. All it requires is 33 magic. If you've made it this far, I suspect you won't have any trouble with the magic requirement.
While you're at the Hair of the Dog, now's a good time to run around to the trap door behind it. While it's described as 'exploring' the tunnel, in reality, all we had to do was step through the secret door in the cellar wall. If you've already leveled Zachary Bragg in Temple Trekking to 99 (you lucky dog!) then it's easiest to enter the tunnel from the backside. Or toggle the shortcut off. Otherwise it skips you past the part you'll need.
This next part is pretty cool. Not because it's harder, easier, or interesting. But because it's associated with the rewards from the medium Morytania tasks. The task involves making cannonballs while in Port Phasmatys. All you need is a steel bar and the ammo mould. The cool part is that once you've complete the medium tasks, forever after you'll do cannonballs in Port Phasmatys twice as fast as normal. Since the bank is just across the street from the furnace, that's a pretty cool deal. At least, if you're a do-it-yourselfer, or if you make cannonballs for sale.
Wearing the legs, you can:
Smith cannonballs at double-speed in Port Phasmatys.
Teleport to the Ectofuntus slimepit 5 times daily. Very cool if you're training prayer.
Any time (wearing the legs or not):
Get noted planks daily from Razmire.
Have your West-Canifis mushroom patch protected from disease.
Get 13 bonemeal and slime daily from Robin, in exchange for 13 bones. (Another great option for Prayer training.)
And finally, the haunted beings in the Abandoned mine won't bother to attack you any more. Not that impressive. I haven't been in that mine in years. But still, you never know!
