See my Patch 4.2 Rare Pet Briefing Post for an updated guide on how to tame Solix, as well as the other 9 Patch 4.2 Taming Challenge pets.
Solix is a rare orange lava spider being added in the 4.2 Firelands Patch. He can be found in the Molten Front, within the Igneous Depths.
Solix is among the eight new Taming Challenge pets, so he requires a little more planning and effort than the drop a Freezing Trap and tame types of pets.
See my Patch 4.2 Rare Pet Briefing Post for an updated guide on how to tame Kirix, as well as the other 9 Patch 4.2 Taming Challenge pets.
Kirix is a rare spider that will be added in Patch 4.2. He is among the eight new taming challenges that Blizzard is providing in the Firelands patch. Each one of the eight pets is supposedly going to require the hunter to approach the tame with some sort of strategy.
The difficulty with taming Kirix appears to be his Toxic Presence buff which causes nature damage to all nearby players. The player in the video mentioned only being able to survive within it for about three seconds, so it hits for a considerable amount of damage.
Another new Spirit Beast has been discovered on the Patch 4.2 PTR. This latest spectral kitty is known as Magria.
Magria not only looks nearly identical to Ankha, but also poses the same taming challenge. According to this post in the Petopia forums, you must remove your armor before attempting the tame, as Magria’s damage scales with armor rating just as Ankha’s does.
