The X% chance to set a status is determined by the
Minimum Attribute Amount . The amount in the attribute needed is determined by the Skill Level of the Skill. There is a table in the above link.
Ex.
Battering Ram It has a Skill Level of two. So you need 8 STR to reach the base %Chance of 50% chance to knock down. 9 STR would make it 55%, 7 STR will make it 40%.
Each point in a saving throw decreases the chance of a status effect hitting by 10%. Like
Willpower .
