Playing D2R offline- What content or items are not available in offline SP vs Online

Hello all. I mainly play solo D2 offline and was wondering what items and/or content is not available to me while playing offline. Sunder charms, certain rune words, ubers, torch & anni etc. Most of the differences online i read only reflect the multiplayer vs solo player differences and not which content or items are available in online vs offline play.

thanks in advance
