I have a question....
What's the different between absorption lapis and safe lapis?
If absorption lapis lv5 + 50 absorption and safe lv7 + 50 defense. I know only safe lapis will give u also some extra hp, but what's the biggest different?
The difference is in damage calculation. Absorption is removed from the total damage after the damage has already been calculated, whereas Safe (which adds Defense) is factored in to the damage calculation.
The end is result is usually that Safe provides a higher damage decrease when hit with right ele, whereas Absorption provides a higher damage decrease when hit with wrong ele. Absorption also effects skills that have a "fixed" amount of damage, whereas Defense doesn't.
From a pvp standpoint, Safe is usually better to link, unless you can get 1.5x the amount of Absorption as you would with Safe Lapis (ie if you could link +50 REC or +75 Abs, the Abs would be better, but if they were the same values, the Safe would be better).
