Everyone always brings up the “math” about pre-nerf cthun. Its this mythical, non-sourced comment about some calculation that showed it was “impossible” to beat the boss pre-nerf. I’ve never seen a source or anything that shows what the math actually is.
Pre-nerf cthun wasn’t impossible mathematically. If you want to make that claim, BACK IT UP. Otherwise, please recognize the fact that the main change to Cthun were bug fixes. The bugs are what prevented people from killing him, not some anomalous numbers crunch
