Opinion on minimum stats to complete a hardcore run?

I want to do a hardcore run as quickly as possible. What’s the minimum level, strength, sword etc. that would be recommended? I’m currently about halfway through the campaign at level 9, 9 strength, 8 sword, 7 agility, etc. Am I okay to just play the main campaign at this point and not worry about any more side quests

If you really want to just chug potions
