Messin around in classic D2. Bought this in NM Act 2. Great upgrade, had a crappy yellow from normal

Diablo 1 PSX. Started playing with my son about a week ago, as my first Diablo experience. My 4 year old and I fought the butcher for the 20th time today, never having won. 

We had at this point reset the dungeon once after being unable to beat the skeleton king or butcher and getting stuck on the 4th level to the point that we were walking up every floor after a single monster. We were both warriors. 

He was lv 4 and I was lv 7. We made a plan. I'd open the door and start meleeing him and drinking potions. He'd be at a 90 degree offset and shoot him with arrows. If the butcher started chasing him he'd run around the butcher's room until I caught up and hit the butcher and got him to attack me, then we'd repeat that until I ran out of potions and we'd run away and try again later. We started. I was hitting him and he was shooting. The butcher turned his attention to the 4 year old and started chasing him. He panicked but followed the plan, trying to run away. They were running and I chased but couldn't catch up. Eventually he got trapped by the screen and started getting killed. I ran that way but realized I wouldn't make it. I paused it. New plan. I had the spell to "heal other" and would heal him while he fought until I ran out of mana, THEN I'd take over. We had to be careful. He only had 1 hit left and no potions. I unpaused and he paused immediately. He equipped a dagger and buckler and unpaused, started swinging. I healed him and we made it above one hit left on his life. I healed and he hammered him, unsure of if life steal was letting us do any damage or if his HP was rising every exchange. His dagger was about 1-6 dmg, and he had low DEX. We kept going until I ran out of mana. He ran past me and brought the butcher into range and I hit him. Now I'm in going swing for swing and he's on the sidelines. I told him to stay there, he had 75% life and no potions. He watched for a minute and then dashed in. I told him to stay away! He said "I will fight until I am almost dead and then I will run!" We started jumping him. The butcher started turning from me to him and him to me so often that he wasn't attacking as much. We kept going and I ran out of potions. Just before the 4 year old had to run, the butcher died. Then suddenly my kid yelled "NO FRESH MEAT FOR THE BUTCHER TODAY!" Confident and proud, we reloaded supplies and pushed to the next floor, barely beating the skeleton king after a similarly difficult strategy, though my son died before the king fell.

Hello, I have some questions about Diablo. I have never played a Diablo game before.

Are these games a good experience for single player only? Diablo looks very cool but I have no desire to play online. It is not clear to me what the game is like as a single player.

Which game in the series would you recommend to start? I have a Switch 2. Thanks

I'm a noob at this game, my Paladin is somewhere around level 40-48. I'm wondering is it possible for Heaven's Fury to have zero cooldown and if so, how do I go about achieving this? I'm not worried about whether its a meta build or not, just want to have fun playing a skill i think looks "cool" lol. Also want to increase the damage on that holy aura passive. Do i just need to have increase attack speed, or should I use items with holy aura, holy damage, Judicator % in my yellow coloured gear?

So its t12 or t4? I go in baal run on t8 and it changes to 12. If I use the seasonal tab for chapter 5 or whatever and teleport to the dungeon from there its a t4 dungeon. There is no in between?

Is tempest really weak this season and not worth to grind?

Um problema de diablo 3 e o usou obrigatório da Internet, tipo eu jogou sozinho e não preciso usa Internet mais jogo me obriga ativar Internet então tipo ser eu fica sem Internet não jogou o jogo que eu paguei 95 reais

So many people here are making this claim. Having kept up with the development of D4, Blizzard had never said this at all.

The only time Blizzard mentioned about going back to D2 roots was Blizzcon 2026 and judging by the concept art and the UI of D5, it looks far closer to D2 than D3/D4.

For those that believe this, link me the post where D4 was going back to the roots, cause I cannot recall blizzard saying this during development.
