Sorry i am not able to help you. Would there be a way to make saves vs statuses (knocked prone, charmed, etc) use ability scores like strength as opposed to armor?

So lets say someone uses battering ram.-Can the person use the skill get a bonus from strength?
The save to be knocked prone won't go off of armor but a random roll using bonuses from either the player's strength OR finesse scores. (either hold their ground by being strong enough or dodge essentially).

Since D&D uses a d20 to determine the results i dont know how to implement this into the system. maybe a flat result for all skills, lets say normally it would work about 50% of the time without bonuses. Then with bonuses since the cap in divinity is 30 for every point above 10 it would add about 3% to the rammer or subtract for the defender.

I am asking because of how D&D works.
