Map iiq + self iiq + party iiq

Additive or multiplicative?

You got that piece of info on wiki, self IIQ and party IIQ are additive and map IIQ is multiplicative.

I still do not find where it say that map iiq is multiplicative could you please post where you found it? I may be just blind thou :D

Also:

2 members
100% self iiq
200% map iiq

would this result in

(1+0.1+1)*3 = 6.3 times the loot?

Check 'partying' page.

If you got 3 party members that's +10% quantity for normal items and 50% for currency for each member over 1, which is 20% increased item quantity for normal items and 100% for currency. Also let's say map gives you 80% more items dropped and the player killing the monster has 30% increased item quantity the total value would be:

(1 + 0,2 + 0,3) * (1 + 0,8) = 2,7 times more loot than normal and...

(1 + 1 + 0,3) * (1 + 0,8) = 4,14 times more currency

Now, if you want to also account for rarity and the killer has 240% increased item rarity it would be

(1 + 0,2 + 0,3) * (1 + 0,8) * (1 + 2,4) = 9,18 times more magic, rare and unique items

That should cover it, I think.

"Any quantity bonus from a Map is multiplicative with all other modifiers. " writtrn, right after what party member does to iiq.
Somehow this managed to escape the grasp of my eyes. :D thanks for answering me twice :P
