You know you're an old-school Diablo player when you remember:
King sword of Haste would be the correct term.
Obsidian Ring of the Zodiac
Fighting Gharbad the Weak, Arch-Bishop Lazarus, and The Butcher.
Fighting zombies that permanently remove health, gaining spells lvls from reading books that you found, apocalypse was the best spell in the game, people didn't know when you were hostile on them, and D1 being the most hacked game in the history of online gaming.
Torn Flesh of Souls, anyone remember that? (unique rags)
Gladiator's Bane, Arkaine's Valor, Harlequin Crest, Stormshield, Eaglehorn, Windforce, Cranium Basher, Schaeffer's Hammer, Doombringer, The Grandfather, and Lightsabre along with many others were all unques in diablo 1.
*Edit*
Oh ya, and lvl 40 was a pretty high lvl. I think lvl 60 was max?
