Play with as few as 10 minifigures or up to 100, it's up to you! We recommend starting playing in the Medieval Era, so find all the medieval and ninja minifigures you can. Swords, shields, and bows will make up the majority of the equipment you will need. Don't worry! If you can't find the exact minifigures or equipment you need, feel free to substitute pieces.
We recommend playing with at least 6 six-sided dice (3 for each player), though players can always trade off dice. You will also need at least one 20-sided die. If your access to dice is limited, just use a dice simulator! Many are freely available, see below.
For your ranged units, you'll need a range finder. Any LEGO construction 22 studs long will work, see above or the range finder pictures in the instruction.

Play matches a small or gigantic as you want! Scaling can lead to matches lasting 20 minutes to playing over multiple days. The choice is up to you!
