Fireball range marker - supportless

I cast… Fireball!You did check the size of the room first, right? RIGHT? Fireball is one of the most well known spells for Dungeons and Dragons. It has a wopping range of 20 feet (8 inch diamater).Luckly our party mage hasn't burned my Druid-fur yet, but we are still at the start of our campaign 🤣Use this fireball range ring to meassure out what area is affected by the fireball.It has 2 variants:8 inch radius, borders excluded (so 9 inch in total): everything that is in the border, is on fire.8 inch radius, borders included. Everything in and under the border, is on fire.Sadly the range is to big to print on a A1 mini. Enjoy!
