After 3 days catacombs is opened on Secura here are the calculations:
From this we can make an estimation of how much essences has been looted , since all of this 3 monsters have the demonic core essece as semi rare drop (1-5% chance) then we can do some calculations:
Using a fixed drop rate of 2.5%, the calculations would be as follows:
- broodrider inferniarches: 122402×0.025= 3060(approximately).
- gorger inferniarches: 120797×0.025= 3020(approximately).
- sineater inferniarches: 118716×0.025= 2967(approximately).
Total estimated drops: 2299+2271+2235= 9047demonic core essences (catacombs opened!!).
This is data from 26 , 27 and 28 of November.
That calculations I made are with a average 2.5% drop of the essence but the range of drop is from 1% to 5% so in the image below you can see the minimum essences dropped and maximum.
On 28 november after 3 days catacombs are open on Secura. after calculations the range is between 3618 (1% drop) and 18095 (5% drop) so with a high probability the amount of essences needed to deliver to open catacombs is on the middle of that range;
(3618 + 18095) / 2 = 10865 and if we round this number we get the value and the answer to this question:
10000 Demonic core essences
