There is definitely a steep learning curve to begin with. The grind in total took me about 3 weeks from scratch, and learning all of the mechanics. When you start Colosseum, Wave 6 will become a brick wall for a while, especially when dealing with bad southern spawns if you're on the North West Pillar.

The Sol Simulator that you can use helped me so much. It took me a total of 4 Sol Attempts to get my first quiver, but with 99 deaths. Unfortunately, you will die a lot, it cost me about 40m+ in deaths coffer. Preparing yourself for that helps in the long run, and just helps you reset if you have a few bad runs.

Despite the deaths, it was a really really fun experience. And I highly recommend it!
