A. Effective HP takes into account the enemy's hidden stats "PDRate" and "MDRate". These values are a multiplier against all damage to the mob. If the PDRate is equal to 10, then all of your damage is reduced by 10%. If it's 90, then your damage is reduced by 90%. Instead of listing another variable, the HP values here are listed to take account for this reduction in damage. The problem in the Maplestory data is that two mobs can have the same HP but have different PDRates/MDRates. For example, imagine two mobs with 1000 HP each, but one has a PDRate of 0 and the other has a PDRate of 99. For the first, you would have to effectively do 1000 HP worth of damage. For the second, you would have to effectively do 100,000 HP worth of damage even though both mobs have the same amount of HP. Using effective HP simplifies these reductions and allows you to properly divide HP by EXP to find the best suitable mobs for your level.
Monster Defence System
Monsters got a new variable in the WZ files which says how much % damage is reduced from your attack.
This variable is called PDRate and comes in 4 forms:
10, so -10% on ALL your attacks. This applys for almost every normal monster.
20, so -20% on ALL your attacks. This applys for some normal monsters.
50, so -50% on ALL your attacks. This applys for some major bosses (Zakum and Horntail for example).
70, so -70% on ALL your attacks. This applys for one BIG boss: Pink Bean. This gives him a HP similar to SEVEN billion right now.
