Can I dual school at level 100 now?

Greetings,

My death is level 95, how soon can I start dual schooling effectively? I'd like to use fire spells like raging bull etc. to do damage, while using death spells to keep me alive, just for some variety.

If I read old posts, it sounds like I won't be able to do that until max level basically, but I've also read that some level 100 gear lets you dual school. I am hoping someone can clear it up for me. Can I start getting good dual school gear soon? Or is it just a late game thing still?

I've returned to the game to try this stuff out. I'm not saying this is great change, but I am interested to try it.

Thanks in advance
