After report from the community that the difficulty spike could be very high, we've balanced enemy health and damage.
Combat will still be challenging and you may need to upgrade the world in order to progress past some areas.
If you haven't upgraded any nodes, you will likely not make it past day 3-4. It's a roguelite after all. :) With experience you can make it even further with less upgrades.
Make sure you explore the world and chase down nodes with stats that can support where you're weakest.
