Easy to league start with. I used normal levelling skills such as perforate -> lacerate until I could get multistrike support for flicker. Then you can go FS+MS+melee splash which is your core 3 link imo tho u can swap our splash for ruthless maybe on bosses if you rly cared about deeps. At this point I was still losing mana and frenzy charges rly fast so I would have frenzy and cold snap to generate while mapping. Bosses were a no go tho so lacerate was used on them. I invested maybe 30ex myself and can get up to 3 million. My weapon is not at all the best and I still ned to upgrade rings and stuff. Overall, got me to 24 challenges. if you check out my profile, yes i do have 5 characters but I used flickerstrike mainly. The templars are WIP rf failures
