Don't upgrade weapons (including pyro flame) above +5 or raw/fire 0
For max dark bead damage use dusk crown, bellowing dragoncrest ring and power within. Can mess with red tearstone for more damage, but it's overkill. Perfect build for helping onebros if they want it.
Use this for PvE and gank squads. Don't be a dick.
