No, the code is different but the damage is similar to the poison so I saw no point in leaving it in. Also the bug is that it always burned enemies instead of having a chance to burn them.
I have like new 5 enemies already fully implemented in the game but I just have to add them to certain waves, unfortunately, you will have to wait a while until I start working on a new update, sorry, I am just really tired of working on this game.
