Are you ready to use the D4’s and create some epic tales? Caltrop Core is a TTRPG system that was created by Titanomachy (@titanomachyRPG) where your d4 (or caltrop) is the key to your success or ruin. There are now over 200 different Caltrop Core games for you pleasure thanks to two very successful Jams on Itch.io. I highly recommend checking out the unique pieces with a wide range of subjects. Each game will have their own rules and theme that will bring this d4 system to life.
