Hello, It's Maetdol Games.
Here are the patch notes for update v1.1.1.

'Nightmare Extractor' allows players to erode their weapons directly to strengthen their builds in the desired form.
'Reforger' allows players to select Reforge they want on their weapons, broadening the scope of builds.
We have adjusted the order of Contracts, prioritizing diversity over strengthening builds.
The prices of Contracts have also been adjusted according to the new order.

During battles with flying bosses (ex. Sol Dea), players often need to attack while in the air.
Due to the weapon's attack speed, there were instances where it was impossible to hit enemies in the air.
While this is an unavoidable characteristic of the weapons, we deemed it unreasonable for SP Attack consuming SP to also fail to hit enemies in the air, and have thus modified SP Attacks to be usable in the air.
We are running a Nightmare: The Lunatic Discord, so please join us!
