This has become the only way for me to play Diablo 1. It is really good and I never know where to start when I want to recommend it to people just because of the sheer amount of content this mod has. Only thing I wish is that the Hellfire content was included. I want the Oils back that apply a permanent +1 to weapon Damage and Hit chance, I want the Hive levels back, those were my favorite Dungeons in Diablo, The Traps can be reworked to instead be Rune Stones that, like the Oils, can apply extra Elemental Damage to weapons and Defense to Armors, I want the Monk class back, reworked with abilities focused around unarmed fighting and staff fighting (could add fist weapons like Cestuses that make use of the Unarmed Attack animations that the characters have but no sane player would ever see because you need to not have a weapon equipped to see them normally) - and since each class has a "Dark Mirror" version of them in this mod, perhaps the Monk's counterpart can be a Rakshasa that can shapeshift into various Demons (I would have suggested Druid but there aren't exactly any animal/were sprites to work with). That's all I feel is missing to make this the perfect version of Diablo 1.
