Unsolved Mysteries

Some people just like exploring and trying to solve puzzles.

Here's a few ponderous things whose solutions are definitely not well known.

Note that there are of course many more and harder things to do, getting to big mobs, tricky areas, etc, but here I'm more interested in little things, that probably anybody can do. Small ponderous things.

If anybody wants to shoot the shit about these, let me know.

Dobra's Recipes

Dobra drops recipes that in my experience I haven't met anybody who knows where to find all the ingredients or what they do:

The first is all 'aquatic stuff'. 2/4 of the ingredients are yet unknown to me.

You take a closer look at a piece of paper in inventory...

The second recipe is all 'desert stuff'. 3/4 of the ingredients are yet unknown to me.

Tudrulk the Shaman

In "From The Stars" is Tudrulk the Shaman who says this:

Tudrulk the village shaman says 'I am waiting on supplies from Tar'pa Cithm, until then there is little I can do. '

Now, there's also a room in the area which is accessible by teleport-only, which contains a suggestion box for Sarakin, the area author. Within that room's description however is the comment ""Have you figured out the shaman yet?"

So, what is the puzzle here? What is this guy waiting for, and what happens if you find it and give it to him?

Curse of Prosperity

Inside the Inn, upstairs, is a mob who wears a ring that you can't get:

A triumphant adventurer is using:
<worn around neck>   (Red Aura) an emerald talisman on a pewter chain

When you attack them:

A triumphant adventurer exclaims 'You can't have it! It's mine!'
A triumphant adventurer clasps her hand around her talisman before attacking.
You parry a triumphant adventurer's attack.

Upon death, they cast invis on the item:

A triumphant adventurer is DEAD!!
A triumphant adventurer says 'You're not getting it that easy!'
A triumphant adventurer utters the words, 'uizug'.
An emerald talisman fades out of existence.

The corpse is then empty, you can't see the item in corpse with detects etc.

This was on an AV and lvl49, perhaps a lowbie is required? Or its just puzzzzlllyyyy
