Escape?

Well your goal was still to escape the 2 rooms and see the outside world.

You had some new abilities that might help. Performing mitosis until your mass managed to break through the door was 1 idea, but again you didn’t want to lose control. Besides mitosis results in you essentially splitting your mass so your actual striking power wouldn’t increase much.

Your second idea was to use morph to change your shape to fit through the keyhole in the door. There were only 2 problems with that: 1 your core was bigger than the keyhole. More challengingly however was the lack of keyhole..... should have checked that first.

Your final idea was to try and simply eat through the door. Your concern with that was the time it would cost. You had no idea how long you had been stuck here and there were still 2 cultists that could come back at any moment. Altough.... those others must have a key, since they were the ones to lock yourself and this girl up in the first place.

So if 2 cultists where coming back, they had the means to enter and exit this place why would you need to eat through a door? Just take the key from them. It would probably end in a fight regardless. Better to use this time to prepare for them to come back right?
