I played with 5BC in the PlaidCTF 2019, playing mostly misc and reversing. This is a writeup of Everland, a misc challenge that consisted of playing a text based action game and defeating a final boss.
I worked on this challenge alongside @EyalItkin who was 100% awesome.
TL;DR We found two logical bugs. One, allowing us to defeat nearly every enemy by making them hurt themselves. Second, we found a way to defeat the boss with an “instant kill” attack.
