In one D&D game I play, we can capture the souls of monsters we defeat and then use them in an arena to fight other teams and win loot. The teams are 3 vs 3.
Problem: it takes fucking forever to resolve. We tried a few things but it's not working really well. It's fucking boring for those not involved.
The DM is considering dropping the whole arena thing but since he invested so much time in it, I'm gonna try to save it by creating a quick resolution system for it.
Basic idea: you find the average of each combat stats for your team (AC, HP, BAB of the main attack, etc) and you check a few tables (one for each stat) and you get a modifier.
Then each team rolls a d20+mods and the higer result win. Best of 3 or best of 5 would be good.
This is still a work in progress since I thought about it a few hours ago
Make sense?
