So if the monster has 50% DEF (notice that DEF occurs in percentages now), you calculate you damage then halve it, and that's what you can expect to do on that monster.
With ignore % defence, you take a percentage of that percentage. Let's say the weapon has ignore 15% defence, and you fight a monster with 50% defence. That means your damage will be reduced by 42.5% instead of 50%. If your up against a monster with 70% defence, you will then do 40.5% of your normal calculated damage.
With just 15%, the damage you do on monsters with a certain amount of defence changes as follows:
30% DEF - deal 74.5% of you normal damage (compared to 70%)
50% DEF - deal 57.5% of your normal damage (compared to 50%)
70% DEF - deal 40.5% of your normal damage (compared to 30%)
With multiple ignore def sources (skills, monster book codex thing), you add the percentages together. So if a skill let you ignore 20% defence, and the codex let you ignore 15% defence, you'd ignore 50% defence in total. Threaten doesn't work the same way, but I won't go into it since you're not a Paladin.
Total damage takes your damage output after defence is considered and increases it by a certain percentage.
So let's say you fight a mob with 70% DEF. With ignore 15% defence, you'll deal 40.5% of your normal damage. With 6% total damage, you'll deal 31.8% of your normal damage.
Someone needs to check this.
