No... you rushed the Act change flag.
The first thing that happens next is that your party runs into level 5-7 mobs and wipes constantly. As you demonstrated by sacrificing a single party member to the bulette.
Here's a tip: open up the console, type warp X/Y and touch the flag zone. Well done you "beat" the content in 15 seconds. That's how useful you have been to EA.
Here is a tip: saying here is a tip makes you sound like a jerk. 😂
I’m not into speed running myself, but I’m not going to s—- on people who do. For speed runners the fun is finding new ways to break the game. There is no cause to be such a sour pus.
He's not doing either.
Speed running in EA is about as useful as someone looking into the code, pointing to the end flag and saying: "HEY, THERE'S THE END FLAG".
It's literally.. useless.
He didn't even break the game in any interesting ways.
I'll spell it out for you: it's a moronic misunderstanding of what EA is designed to do, he did it badly and there's 100% no point to speed-running EA unless you're high-lighting skips / glitches / broken flags etc.
He... did none of that. It's useless to Larian in EA.
