Dota 2 but every debuff lasts until you die

How to add bots: Create a custom lobby, and give it a password, then check "enable cheats." When you get in the game, type dota_bot_populate into the console.

I upped the magic resistance a little bit and made it so all debuff last until you die. ITEMS DO NOT LAST FOREVER

Buffs that are made based on the debuff also last forever (e.g. static link, essence shift)

As a general rule, if it would do nothing then it doesn't last forever (for example glimpse.)

Hard disables do not last forever, silence and mute being the only exceptions.
