Specific Notes[edit | edit source]

I'm only reverting nerfs that had numerical values assigned to them. These could go back to the old days of Dota 1, but not necessarily. You can check the Dota wiki to see the earliest patch I used for each hero.

I will not modify talents, and cannot guarantee that I will program in non-basic old spells. Bolded stuff are things that I'll try to add in, but probably won't be able to; we'll see what happens. Italicized stuff are things that would be absurdly broken (or hero countering) if added, such as stacking magic damage components of spells with physical damage components (this results in massive fucking nuke damage, such as Land Mine dealing 260 physical damage + 750 magical damage when maxed); I'll note them here in case I want to do anything with them in the future. However, I will add special notes of old passives that I might be able to add in (such as DP's Witchcraft passive).

Universal Changes[edit | edit source]

  • All stat gains will be increased by +0.4, to match with the old stat leveling system prior to 7.00
  • All base health regeneration values increased by +0.25
