Finally finished the Skettis questline (assuming nothing more opens up at higher rep levels... can't really think of much to do after killing their god) so here is the scoop:

You will initially get a quest to collect 6 Shadow Dusts. When you turn them in you will get some Elixir of Shadow and it will open up the repeatable rep turnin of 1 Shadow Dust -> 1 Elixir/250rep/8g. Shadow Dust drops like candy at the moment so you should never run out of Elixir and you will gain rep fast.

The Elixir of Shadow allows you to see "Timelost" mobs in Skettis, these are ghostly mobs that you normally can't interact with, much like the mobs in Shadowmoon. Timelost mobs drop Time-Lost Scrolls, which I will come back to later.

Your next quest is to kill 3 named Timelost mobs. They are non-elite and this is fairly easy. One of them will drop a journal. This starts the next step of your quest.

You will be sent to Shattrath, then back to Skettis. Now you will get a quest to retreive an item for someone. Once again, simple and straightforward, it is just where the NPC tells you it is.

You are then sent in "disguise" to talk to an NPC on the island in the center, you have to buy a book from him and take it back to the camp.

Once you have completed all this easy stuff you are given the quest Adversarial Blood. This is the mindnumbing, want to gouge ones eyes out, why oh why would Blizzard do this to us, section of the quest. This quest is to get 4 items from 4 elite mobs summoned from the bonepiles scattered throughout Skettis. They aren't very hard elites, could probably be 3 maned although it would be slow imo. They are not soloable, and I doubt you could do it without a healer at least, and preferably a real tank. They each drop 1 Rare quality item, either a random "of the" item or a specific one to that mob. They each drop 1 quest item, which only one person in the group gets! That may not seem so bad until you realize you have to farm 20 Time-Lost Scrolls per summon, so each person in the group needs 80 Time-Lost Scrolls. The scrolls are semi-rare drops off the Timelost mobs as I said earlier. So yeah.... this takes awhile.

Once you have completed this quest, you receive a quest to kill Terokk. Blizzard has mercy on you here because you don't have to farm anything! Go to the center island and summon him. He is somewhat interesting, and harder than the previous bosses (you should really have 5 for him at least). He does Shadowbolt Volleys, and this sort of "AoE stun", where he chooses someone to hit while ignoring everyone else. I beleive he had some other abilities I didn't personally experience as well. At low health he goes immune, and well, I'll leave it up to everyone to figure out what to do, Blizzard surely won't hold your hand through the final part of the encounter! :p

Terokk drops a blue item as well, nothing special. The quest just gives you a bunch of gold, no rewards.

And that is it!

Here are some of the unique items that drop off the mini-bosses:

Karrog's Shard
Off Hand
Equip: Increases spell critical strike rating by 12
Equip: Increases damage and healing done by magical spells and effects by up to 35

Gezzarak's Fang
Neck
+15 Intellect
Equip: Increases healing done by magical spells and effects by up to 57
Equip: Restores 4 mana every 5 seconds

Here is what Terokk dropped for us:

Terokk's Gavel of the Invoker
One Hand Mace
39-127 / 2.00 speed
41.5 DPS
+14 Intellect
+16 Spell Damage and Healing
+14 Spell Critical Strike Rating
Equip: Increases damage and healing done by magical spells and effects by up to 121

Are the rare "of the" items level 70?

They are all level 70, and it isn't Blizzard confusing you it is me, I am misspelling it (notice it is spelled Terokk in the SS's). I'll go back and correct the spelling.

Ya I deleted my question after your screenshots answered it. The "of the" items are bop I assume?

Purge? Spellsteal? Rocket Launchers?

I have been aggroing these mobs without the elixir active. Hopefully it will be fixed before it goes live (I've reported it), but if you're on the PTR and randomly dying in Skettis like I have been, you now know what is happening.

How is respawn time ? And how crowded do you expect the new quest hubs to be around patch release ? Basically....Is there enough to go around for a mass influx of level 70's ?

It isn't that unusual (At least, any more), it's just a blue spell damage mace with random suffix. The same thing happens with the random green spell damage daggers you can find sometimes. Plus it's been happening before with some random items with fixed stats, I'm pretty sure I remember someone having Dark Iron Boots of Fire Resistance for example.

Its looks to me its because its actually Terrok's Gavel of random enchantment, the 125 dmg/heal is cause of the Gavel and the of the Invoker random enchant that adds the dmg/heal and spell crit.

I'm curious if there are any Bracers of _____ Wrath that anyone has found off these bosses?

I'd also like to known what slots the blue "of xxxx" gear are filling.
