ok I got it now
thank you guys!
The multiplication of probability by % chance was the part I was missing.
I guess the new system was done for the sake of optimization, thought old one was a bit more straight forward (new system maybe a bit harder to explain to a newbie)
One more question abotu exmaples.
Suppose in old system I have following:
lootdrop_entries 85, multiplier 1, prob 100%
lootdrop_entries 85 would have inside:
item1 10%
item2 10%
item3 10%
item4 10%
item5 10%
item6 10%
item7 10%
item8 10%
item9 10%
item0 10%
so only 1 out of 10 items could drop each time with equal chance (old system RND buginess aside)
how this end up looking in new system?
