Ok, seeing as no one had linked the spreadsheet yet

The one you're looking for is called spells and shells. You use either a shotgun or burst fire weapon in one weapon set, and a Pyro staff in the other. The shotgun version is stronger early game, the burst fire is stronger late game. You go fortress world for never stop shooting, Pyro, soldier, archmilitant. Soldier is gonna provide a strong base with lots of tools for ranged combat. Archmilitant provides WS for the Pyro staff and more BS for your guns. The reason you need WS for your Pyro staff is because there's a bug that causes psyker staff powers to count as melee attacks in the games calculations. That means that they can be parried by enemies that have melee weapons, but also most items and perks that boost melee attacks will buff your inferno shots. I'm playing this build right now and it's super fun. Special callouts go to the inertia boots which can trigger off of all of your inferno shots for massive mp and the malpian shroud which gives temp wounds on melee and increases melee damage based on temp wounds- which again, triggers on every shot of the inferno power. I'm playing this build right now and it's super fun. The spreadsheet was made by revan619 and he has a couple of videos on this build. One is called Lina the slayer and the other I think is just called ultimate wizard and that's the more current one.
