Were you playing alone? Playing with a friend I can consistently get to at least wave 23 or 24.

I play public, but its just that the difficulty ramps up non-linearly. It goes from faceroll to instant death in 1 wave

whats wave 18-19? your problem could be incorrect itemization.

Get silver edge! It is great against both Medusa and Centaurs because it breaks their passives. It also helps you avoid getting hit by dusa when running from her gaze.

the centaur level is specifically designed to punish teams that go full physical damage

It doesn't though, Silver edge is too good.

So silver edge bugs out the passives and somehow this is considered good?

BKB also gets rid of the centaur dispersion, as well as the radiance burn. Plus you don't have to worry about wasting the charges, as the next wave you can just get an upgraded one.
Medusa can be pretty difficult without the right hero though.

I do agree that there is quite a jump in difficulty starting at the Medusa wave, and likely in the future there may need to be added a few more waves before Medusa in order to even out the difficulty curve.

Break is an effect, Silver edge does it. It isn't a bug, it is what the item does.

The game is balanced OSfrog watch me went through all the rounds here: https://youtu.be/cyOdnV7LlUQ

Just becuase you can finish it doesnt make it balanced. It has non-linear difficulty jumps, this is my only point.

They guy is just posting his video everywhere, ignore him.

it depends on your items and heroes. medusa is the easiest level in the game if you have a brewmaster on your team and long range magic damage, silver edge, or visage is amazing against centaurs

So it's balanced for some heroes? That means it is imbalanced? Where do these arguments come from? Sure if I pick the best team and the perfect items its easy mode, that has nothing to do with balance.

The first pinned thread is called "Is there any hero you think is very overpowered or very weak". With the body saying "suggestions are welcome". Why did you make this thread.
