main assault 125
2x minor assault 150
2x horrific vision 300
4x Emissary 200
+ 3 * <M+ level>
+ 20 * <M+ level> in weekly chest
This is if you take it super casually, so a +10 once a week and doing the above would net you just over 1000 of the currency, which is 2 essences per week!
How is that as much of a grind as compared to grinding follower xp or rep?
