So with the latest Patch you can get into the Moongolow and the first time you reach 15 minutes you unlock the Holy Forbidden (Hidden Ground). This stage is quite tough the first time you enter it. And really confusing 😀 You cannot enter this with special characters like Leda. The best character to beat this stage is Gennaro. With the Knives you will be able to shoot all the candles and get health to survive. Now you just need to run 😀 After this you unlock 4 mighty new items in each stage. These are also necessary to evolve the Laurel and Clock Lancet! But for the cost to meet a lot more of enemies which are also granted a lot of power (180% curse :D).
I would like to see the rest of the Arcana. So let us go and reach Level 99 with Imelda and get the next unlock. It is pretty straightforward. You just need to be aware of the Evolutions and you should be good to go.
