Version 4.1

“

Druid of the Jungle very recently received a big nerf and while it certainly still is strong, we’re not yet convinced that it needs any more significant changes. For now we’ve decided to just make some small price adjustments. With these changes, it’ll now be slightly more expensive to quickly and easily buy 1xx on your 030 Druids as a very cheap option to strengthen your defense.
