With the base dice system, yes. I’m lazy so I’m just going to copy-paste what I said to the other commentor, lol.
It’s important to note that doubling up on dice in this system is essentially min-maxing. You’re getting a 75%+ success rate on Forcing in exchange for a 0% success rate on Engaging. That is just with the base system, though. I didn’t include these sections in the post, but other systems of the game (such as Effects) meddle these numbers and can allow a double d6 character to successfully Engage.
And no, I haven’t played Fabula Ultima. I’ll be sure to check it out tho if it’s similar!












Either! That’s typically how I’ve played most RPGs when it comes to determining Charisma, Dexterity, etc.
A player might say “I want to try and Force the door open,” determining it themselves. They might also say “I’m gonna survey the horizon. Do I see anything of note?” and the GM might say “Sure! Roll to Engage.”
