Hi guys,
Just to clear things up, this is a sheet I made for 5e. The overall design is inspired by Mad Irishman's sheet for 3.5e, which I have always liked. Since there was nothing similar for 5e, I created a new sheet from scratch and then decided to share it here (with Irishman's consent).
I've been working on it since, recently adding auto-calculation. Please let me know if you have any comments!
