The Legend Calculator is a programme developed for Windows computers which allows the user to enter the links to card pages from this wiki and have it calculate their total attack and defense. The calculations are 100% accurate with altars, frontline card elements and skills being considered. This is a great tool to both model future changes to your deck as well as giving defense leaders an insight into how much they are able to block, a feature not included in the core game.
Currently The Legend Calculator is in an open alpha stage where anyone is able to use it, however may encounter bugs or faults. Posting comments below on improvements would be a great benefit in improving the programme.
