Drop Meditation

Hey guys,i was looking here,

and i have seen every mob have Drop Meditation.
What it mean???

I think, that is the rate to dropp these uniques Items.

drop rank - what kind of items can be farm from mob (normal, rare, unique, realms, etc., also says if u can get buff from mob)
drop meditation - how many items can be farm from single kill (it's factor not exactly value)

and can you write me what mean Rank 1,2,3,4

don't remeber exactly since I remember this from cm game version, but >5 are probably those mobs that u can get realms from, and over 7 are those mobs who gives buffs (like BG bosses)

rank 1 (normal mobs - > drops normal items like normal, rare armor, in webzen also unique armor/weapons)
rank 2 (elemental mobs = rank 1 + unique ring/necklace + special stones)
rank 3 ( rank 2 + elite + ress orbs, ...)
rank 4 (monsters in BG so elite , ... but no lower unique)
rank 5 (rank 3 + realm)
rank 6 (monsters in HH, so rank 3 + HH items)

drop medition = chance to drop something special / how higher how more the chance is to drop unqiue, elite , realm.

Look at ignatus (lv51), (used to be) a hard boss in asylum. he has a drop medition like 12. normal mobs have 1.
(but since he has veru much hp and can kill only 1,, it's better to farm at elemental mobs)

correct me if i'm wrong.

thx for really good teach!! :D
