A week back I posted a link to Lion Rampant – a game written by Daniel Mersey and published by Osprey.
The same basic rule set to Lion Rampant has been updated to provide for magic, fantasy, and fantastic beasts. There are some potential balance issues involved with the magic system, but nothing that can’t be remedied with house rules.
I would recommend picking it up.
It can be purchased here at Amazon: https://amzn.to/2zi7utv
