Effects: As of Age of Shadows, Discordance no longer reduces a creature’s stats: strength, dexterity, intelligence, hit points, stamina, and mana. However, Discordance reduces physical resistance, all elemental resistances, and skills by up to 20% at Grandmaster and 28% and Legendary. Swing rate, damage, and chance to evade are directly reduced; this is in addition to the skill reduction of anatomy, tactics, lumberjacking, weapon skill, wrestling, parry, etc. Discordance still lowers a creature’s base barding difficulty.
The effects of Discordance is halved on creatures with a barding difficulty of 160.
So if this is true and it drops the barding dificulty by 14%(half of 28) that leaves a barding dificulty of 137.6 after discorded now there is a calculator out there im trying to find again that you can put in the barding dificulty instead of the creature either way very good question I would like to know the answer myself if I can find the other calc ill post it here for you but I have now given myself a headache trying to figure it out
