A quick minor run, soloable, but 2 people is a lot easier. Requires 3 of the item a sandstone water glyph to start.
Minimal preparation is required, basic spell mems, reagents and two additional factors; an exotic type damage weapon (fire and a few other elemental types will work too.) and an item with improved invisibility (it will not cast targeted spells if you are invisible).
An Incensed Water Weird encounter
When ready head to Desert Of Thorn and find the oasis pool. Simply "put sand pool" x 3 and a water elemental will appear, attack and kill it.
Note: At this point a broken piece of statue will drop to floor, this can be used for Mark of Famine.
Once dead An Incensed Water Weird will appear, he is immune to most spells and damage types, so only 100% spell lands should be attempted. You can dispel him via weapons before spelling him up or a timepiece if you have one. If you are invisible he will occasional cast TKE and TKW (which might unform you), other than that, the fight is pretty easy.
