There are no dragons in oblivion.
All you have to do is level up, (to about level 30 or higher) then go out in to the forests and the bandits might where glass armor, or even deadric once you are a high enough level.
you level up and then upgrade your magic skills
If your a high enough level (somewhere around 20) you can get them from either the dark brotherhood or off of a creature in oblivion.
I'm guessing a relatively high level... probably between level 25-30
If you mean DAEDRIC armor, you need to be high level, at least level 24, and it will start appearing on Dremora and Marauders.
it doesn't matter what level your player is but it does depend on what areas you go to, but in oblivion your level of difficulty depends on how strong the daedra are.this is from experience. im a level 40 sumthin nord.
you use them
go to documents go to my games go to oblivion go to saves
I hope you go to Oblivion! I hope you fall off High Hrothgar!
Once you get high enough level, like 15 or something, bandits will start carrying glass daggers, glass warhammers, you name it. It is based on level, not location.
Buy or find them.
