Relic crystal probability
If you roll a 16 sided die 100 times the probability of hitting each number at least once is .99999818 yet I’ve opened nearly 100 batllecast relic crystals and there are 2 I still have not rolled. The odds of this is almost impossible if it was actually random as in rolling a 16 sided die. Are these crystals actually random? Not complaining but it is actually really frustrating when you look at the probabilities. Any insight from the community or is my math incorrect?
