Ima just do the mafs.
I’m assuming here the time to crown code farm is 3 minutes including rejoining making the file etc. (To get 2600 crowns)
The chance for a specific drop for the minotaur is 1/40 so you’ll have to kill him more or less 40 times to get the vastira and I’m gonna assume here again that each kill including the time waiting for him to respawn and travelling to the location is 5~10 minutes for consistency. Now 40x5 and 4x10 is gonna give us 200 and 400 aka 3 hrs 20 mins and 6 hrs 40 mins.
That means you’ll have to crown code for in between those times, now 3 mins x 67 which adds up to 201 [3 hours 20 mins] and 3 mins x 134 which adds up to 402 [6 hrs 40 mins], [Not exact values for simplicities sake] then multiply 2600 with the numbers we multiplied the mins with which adds up to a total of…
174,200~348,400 crowns.
(I basically did the maths for how many crowns you would make for the same amount of time you grind minotaur, keep in mind a lot of the values are kinda scuffed and are an estimation. If I did anything wrong please say so cuz I didn’t bother double checking shit tbh lol. Also keep in mind this is far from exact I would need a shitload of data for it to be fully accurate, something like 400 minotaur kills and time it which I’m not doing)
