Garments start appearing in vendors inventories once you reach level ... 8 or 9.
And most of those have bonuses.
Same as the belts start appearing only then. With bonuses too.
Currently, several equipment items are very underrepresented. Belts, garments, helmets and boots.
There are only cloth and those winged metal helmets in the game now, until you get to very high levels. The effects they give seem very limited.
Only basic leather boots (with different effects) until you get to level 8 or 9.
Rings appear more rarely then before too. While their effects seem to be less varied. But that might be just my experience...
