I wonder if you ever considered that creatures such as yours would use their tail as a weapon (with an attached blade or hammer etc.)?
With my Desert Yinglets I base their main weaponry as their tail, what is the most muscled part of their body.

Oh completely. They will put on a "tail mace". Axe not so much as it needs a bit mor eaim. But the tail mace, usually made of a hollowed stone, or sand filled leather is quite common.

Well I think a heavy thing is not that good for a tail based weapon. It may cause a loss of balance and also could cause dislocation of the spine if its swing too hard with out a hit...

Originally first I saw such a thing only in one game: Albion (dos), and in that game the catlike Iiska were limited to daggers only for their "tail weapon slot".
Tho they are a feline like race with a thin tail.
Thank you for your time!

Not a problem. Loved to discuss these things. The JaggirI tail is thick, and string and well attached, it's also springy and somewhat stiff.

As far as I know (based on my velociraptor derp skeleton), only about a third of the tail from the waist are flexible to all direction, the rest of the tail is made from tube like bones.

Anyways I have a hard time imagine a method to utilize even a blade with such tail structure. Like ok, running with a side tilted tail pointing at neck height is easy, but thinking about a something like spinning and jumping with an intent... -.-

I would be amused to see a 'modernized' Jaggiri, say in todays US Special forces gear and garb!

You mean like this?

Imagine a Jaggiri in dockers, ray-bans and a polo shirt.... Trying to get you to save a bunch of money on car insurance.
