/quotes and whatnot "The PLD is hit with an attack that would do 100 damage to the PLD, but 300 normally to the "coveree" (just an example), the PLD has a chance to block the attack to reduce the damage, and a percent of that would transfer to the "coveree", so if transference is 20%, the "coveree" would only get hit with 20 damage instead of the original 300, with the PLD getting hit with 100 not calculating the damage reduced from blocking." /endquote and whatnot.

Here you have the PLD getting hit, and the DD getting hit, the PLD in turn takes the hit for the DD taking most of the damage. But the PLD is already getting hit by the attack (since you added cone attacks and the like in your original description) therefore he is taking two instances of damage from a single attack. If that is not what you meant then be more clear, for that is how it reads.

A working solution would be to have a single target behind the PLD taking reduced damage with: 1, the PLD takes no extra damage in this instance, 2, the DD does not have to have the highest enmity at this point. In turn, this would literally make the PLD a shield of sorts as you see in movies where the knight protects someone from dragon fire with his shield. The knight would take the hit and his ally takes less damage for it.
