First of all, thank you for choosing one of the creator tiers.
Creating and designing a weapon, portrait, NPC, boss, enemy, statue, stained glass, playable character or secret area is exciting and we can't wait to work with you!
So what are the flexibilities and limitations? You are absolutely free to design in any way you want, as long as it is your own idea and not using other intellectual properties. We suggest to keep in mind the core themes of The Last Faith, though.
An example of creating a custom weapon in “The Blacksmith Master” tier is as follows:
You can design a pistol sword with your custom name and story, with some of the custom details you have created and also a particular moveset, secondary abilities or special attacks. (Of course It doesn't have to be a melee weapon, it can be a distant weapon).
