Here's the POB for my map blasting cold Spark Inquisitor and level 72 Hollow Palm leveling setup:

This is a popular high-end take on cold Spark specifically made with the defenses to trivialize juiced T16 maps. If you wan't to start with Inquis Spark, don't use this as a guide, use the AnimePrincess guide I saw posted here the other day and work toward auras/max res stacking later on. I'm mostly sharing this to get Spark starters excited and also share info on what's possible with mapping to level 100.

The timer is just following along with the in-game /played character timer and I bulk bought maps, compasses, and scarabs with my league character intermittelnly throughout the process. Its just for fun and entertainment so let me know if you have any questions.

I also highly recommend Sparkers and other spell casters to try out the mastery for opening chests on 25% of spell casts, it was great QoL with Abyss, Breach, Legion, Strongboxes, Blight, etc.
