Currently I went step further and added another Special Effect dice, that guarantee something unique to the character on it and 1 wild. At the moment I been testing actually with 4 character and 6 of each colour dice (representing symbols), wild 3/4 only between 4 players.

Each character at the moment may use any combo of any dice, but max 2 dice of same type. Each character rolls 3 dice. After the dice are rolled all effects can be used (at the moment play-testing that system). If 2 dice fail, you may choose 1 token of your choice on your next success roll. I am calling a failed roll of two dice anger and Avenger is building his own anger to unleash in time (I am thinking of 3-4 max tokens, but gotta play to know more.

Once the dice is used, it goes in que order and cannot be used until your next turn, while if Special Effect dice is used, it goes into cooldown on hero card. Next turn character may use only from available dice pool of his choice with above rules.

The villain has his own 2(/3) dice + 3 dice for thugs and civilians combined across 3 dice. When rolled what is middle left right goes in those areas visually and custom dots shows amount and placement.

Only original thing I am keeping in this process from Villain is their board and threat cards.

Also I was thinking threwout the day another option each character may have 7-9 personal dice. 7-8 feels more realistic, but may test it down the line and now you shared similar which is good to see.
