Golly
If you're following us through Act 3, Golly is your final boss. Before you can fight it, you'll need to make sure you've interacted with the radar dish in the Magic zone to unlock the Factory. Once inside, you'll need to go around the map and use the ladders to climb up and turn the dishes around. Doing this in all four corners will finally give you access to Golly.
Golly
Golly is probably the most interesting fight in the game. We're actually not sure if it's possible to lose, though we may have just gotten lucky in our playthrough. The fight starts with Golly connecting to the internet. You'll then see her use cards with photos from the web and later photos from your Steam friend list.
After a bit, you'll be given a card from someone on the internet. In our experience, this card was pretty solid, but we assume there's an opportunity for other players to troll you. That said, it seems that you only get a card from a real player if you both happen to be playing the boss at the same time. Either way, here's the card we received:
From there, you'll quickly make it to phase two and will be given the opportunity to create your own card. Golly will try to send this to another player. If someone else is playing the boss while you are, you'll have to wait and see if they win using your card. If they do, you'll automatically win the fight. Therefore, we recommend sending a good card and helping out your fellow players.
Presumably, if there isn't another player available, the card will go into your hand, and you'll have to fight her the old-fashioned way. We were lucky enough to help another player out, but your experience may vary.
Either way, you'll eventually deal with Golly and be ready to move on. Congratulations. You're finally in the end game. Make sure to check out our Ending Explained section if you need some help understanding Inscryption's wild ending.
