Savage sweep + rampage blessings AND unarmored + flak damage on the chainsword will melt through hordes and easily deal with specialists+elites. Weapon special for heavier enemies like Ogryns and Bosses. Either chainsword mark works, up to preference.
Full bore + deathspitter blessings for consistent one-shots on short-medium range. Pairs well with Weapons Spevialist. Though point-blank, the assault shotgun will one-shot all non-ogryn enemies besides maulers if you fire both shots. For maulers you'll need full bore or other damage buff. For perks, maniac damage to easier one-shot mutants + ragers and reload speed TO SHOOT MORE.Since Weapon Specialist reloads the shotgun for you, consider dropping reload speed perk for something else.
Both krak and frag grenades work. Chose krak grenades to easier deal with Ogryns and Bosses. Whichever you pick, you'll regen them quickly with both Demolition Stockpile + Demolition Team.Fire Team for extra damage and convenient for talent tree.Weapons specialist to easily reload the shotgun. Allows to quickly switch between melee and ranged. Reload through melee -> quickly one-shot priority target -> switch back -> repeat.
