Calculating Credits Gained From Bounty
every regular monster, mini-boss, and boss monster have a fixed amount of credits drop. the drop will be skewed a little with RNG. Artifacts (and possibly buffs) that affect credits drop will be applied to the "fixed amount" instead of the final credits drop. The formula below will explain the rate"F = ( (B x A) x M ) x R"

F = Final Drop Rate (you gained this amount after the monster is defeated)

B = Base Drop Rate (every monster have base drop rate)

A = Artefact (modifier by artifacts : Bag of Greed for regular monster, Chest of Greed for mini-Boss and Boss monster)

M = Extra Modifier (gained from buff, video ads)

R = Randomizer (the game will randomize the drop rate roughly from 0.8 ~ 1.2)
