so what I was thinking like maybe add a spirit multipliers that goes up slowly like form 1x to 1.1x each upgrade and it costs void essence which you get from defeating the conjuerer. The price doubles every upgrade and the conjuerer only drops about 1-5 essence every kill (is affected by luck but less than other essence, for example let's say 100 luck = 1 more essence drop from mob kills but for void essence it's 200 luck = 1 more void essence, get the idea?) I think this'll make grinding a little less tedious and make players play more darklands even after getting a void wand.
