I know that the usual path for gears ia desert scorpion->menace->desert storm->joser->osiris->himmelmez->cazar.
However, there are also other gear sets. I know that for ML 21 there's old ashkaron and basilisk and that they together can be crafted into ashkaron (ML 25 instead of 21, interestingly).
I also heard something about "mustafa" and "witch" but don't really know how they fit.
I'm assuming that visually old ashkaron, basilisk and ashkaron all look the same just varying their colors, just like the previous sets, is it like that?
How do other gears fit into the scheme, both in progression and specially in looks?
Are there any more sets that I'm unaware of?
I'm stressing this: my interest is purely cosmetic. I know that 21-25 gear is useless and I don't care. However, I do want to get some version of all these sets just to see how they look.
