Knockdown and stun make a creature vulnerable to a coup de grace, but is there a difference between the two? And more importantly, how is the success of a knockdown/stun attack calculated? There are effects adding "+25% Knockdown" but without some basis for calculation I don't know what that means. Do creatures have a percentage resistance, so that the total chance of a knockdown is (Base percentage - resistance percentage)? Is it simply your base chance of success calculated without the need for any stats from the bad guy? I know some people may think this sort of analysis takes the fun out of a game, but before I invest talents in these abilities I want to know if they're going to be useless when I need them most.
Next, what does pain do? Presumably it makes it harder for them to hit and/or dodge/parry, but how much so? And again, what does "+25% pain" mean?
And how about hex and fear, and anything else anyone can think of?
I don't know how anyone else will know these things, but I thought it was worth asking
Thanks
