This looks awesome! Could you explain how one does an "I've heard it both ways" roll to help out?
Absolutely! So, in terms of mechanics, your 'I've Heard It Both Ways" roll needs to succeed based on the number the other person is trying to meet or beat. So if they're aiming for 4 or higher, you can assist them with your own roll. If yours succeeds, they add 1d6 to their dice pool before making their roll. "I've Heard It Both Ways" needs to be declared before the person you're helping attempts their roll.
Let me know if that helps!
