How exactly does holy symbol work now (Post bb)

from my experience and from reading other forums
you have a 1.1 x multiplier for solo hs or non leacher hs

if the party of 2 or more can take exp the multiplier becomes 1.5x

ive yet to confirm this but ill be doing some testing soon now that i have 3 comps beside each other

one of the following is true

a) exp is only 150% increased and split between killer/leacher(s)
b) hs actually has different values assigned for different number of leaching members (which is not my first choice of most likely)
c) nexon implemented bonus exp multipliers for larger party (and no im not talking about the 2nd exp line, party bonus exp)

ill keep this posted after my exams this week
