Do you get them if you kill the boss in a map?

As of now I havent gotten any in over 100 delirium runs..havent tried to kill the boss tho..

random drop
the more tiers of delirium rewards you charge up the better chance for delirium drops (jewels/orbs)

liniair maps like tropical island best choice. Go to the end as fast as possible killing everthing.
keyword is fast. If youre not fast enough low splinter drop no orb. Appearance of one of the bosses in a high tier map and killing him will give more chance an orb will drop.
Personal experience dont know if it is a fact that it will.

ya im making a new build atm more zoom zoom

Self expose how sloth you are lel

U need to hit 3x then go kill boss u get like 25% chance as i see i farm port with friends and we spam red maps for seeds and if we get dil we go like this make 5/3/1 then rush to boss
