Morytania task set

We know we're getting a Morytania task set with new leg armor this month. I'm going to attempt to guess as many of the hard/elite tasks and possible rewards as I can, mostly just for the heck of it. Feel free to join in if you like. Then when they release it we can all see how much my intelligence dwarfs that of everyone else.

I'll start with the bts quote and then make my guesses.

Morytania Task Set + Early Bird Bonus

Finally this month, we’re introducing our latest Task Set, this time based in the dark, desolate lands of Morytania. You’ll be able to complete sets of Tasks which range from Easy to Elite levels of difficulty, which will encourage you to make snelms, activate medallions, slay barrow wights, and brew your own prayer renewal potions.

Tasks are all well and good, but it’s the rewards - including new leg armour - that really interest a fearless traveller. Fancy halving your prayer drain while in the Barrows? How about increasing your trekking rewards and your mushroom yields from patches? All that plus more, and over 150k in XP lamps! For those who are really keen, we’ll even add an Early Bird Bonus (worth 15k) for anyone who completes the Easy and Medium lists within the first 2 weeks of launch.

Elite Tasks

Catch a baron shark in Burgh de Rott.
Kill an abyssal demon.
Cremate a fiyr shade.
Mix a prayer renewal potion. Confirmed in the bts, but I'll go a step further and predict that you have to complete every step in the Morytania area, like the ardy rune crossbow task.
Loot the barrows chest after killing Akrisae.

Rewards

Ability to grind bones faster
Free daily buckets of slime
Teleports to the Haunted farm
Daily teleport to the haunted mine (near the salve crystal area)
Salve amulet bonus stacks with slayer helm bonus (wishful thinking, I'm sure)
Ability to talk to ghosts without a ghostspeak amulet
Pirate Pete doesn't hit you as hard when you go to Braindeath Island (again, wishful thinking)

Anyone else want to take a shot at it?

"Mix a prayer renewal potion. Confirmed in the bts, but I'll go a step further and predict that you have to complete every step in the Morytania area, like the ardy rune crossbow task."

That is the only one of that came to mind, and you already have it.
Nice topic!

I am going to predict growing some different mushrooms is one of the tasks though which idk. Also collecting hollow logs for splitbark armour will probably be another. Use the ectofunctus. Kill a werewolf while its in human form and when its in werewolf form. Complete a burgh de rot ramble and temple trekking round. Use the drakon medallion to teleport to somewhere. Make a ghast visible and defeat it. Maybe make an ivandis flail.

Lame.. what if I don't want to burn a shade

Then no buckets of slime for you.
