BAH you still have your card stacking rates all wrong.
Just to fix your FBH v.s goldenring section: hydra and goldenring are the same thing; both have demihuman bonus therefore won't stack properly with two fbh on shoes. I will demonstrate since your guide isn't very good :/
When you compound one goldenring OR hydra on your weapon you will have a weapon dmg bonus of 1.25% or 1.2% because adding 0.25% means your weapon dmg is reduced to only 25% dmg, so by the game engine describing a card as 1.25 it includes 100% of your dmg PLUS 25%. When you have 1 fbh and one goldenring, your weapon dmg percentage will now be 1.75% because same type adds not multiplies. By adding another fbh your wepaon dmg will equal 1.25 again because the game mechanics were not meant to handle multipliers above 2 so it adds 50%+50%+25%=1.25 this is how you get the goldenring not working properly.
If you use 2 fbh then you shouldn't use any cards that increase dmg against demi-humans as it will not compound properly. Please make sure you know what you are doing before making guides as you will mislead alot of new people.
