Hello and welcome! 😊
In the current state, no. The restriction is by class and level (both together).
Actually, making equipment restriction this way was a deliberate choice. For a maker tool like ACSG, this approach facilitates balancing and offers more exclusivity and personality to each class.
That said, I agree that restrictions based on attributes (stats) or level, as you suggested, offer more flexibility for creating builds, and the class restriction ends up being less flexible, yes.
The implementation of this feature is indeed a future possibility and will be thoroughly considered. For now, I have other priorities in the queue, but your suggestion is registered and will be carefully considered in the future. 👍
Thank you for this great insight and for contributing to ACSG! 💪
