The Sanctioned Migrane - Brain Burst Build
 Psyker Build - Warhammer 40k: Darktide 

Headache Inducer Crit and Weakspot Based Build - "Sanctioned for psychic combat. Unofficially, just really good at headaches."

Flagged during Scholastica evaluation for "excessive cranial output", the report never quite decided whether that meant a gift or a liability...

Brain Bursta! - Works in harmony with the two charges of Bolstered Shield due to Kinetic Resonance and Empowered Psionics leading to rapid fire brain burst on bosses and big bois with Psykinetic Grip. Try and keep at least one Empowered Psionics charge active for Kinetic Flayer to kick in with maximum effect. 

The Telekine Shield - With its buffs its a solid choice now compared to dome and also has offensive utility thanks to Kinetic Resonance. Enervating Threshold is also a solid pick to place behind a fight and make specialists less of a pain. 

Voidstrike Staff - Here for Gunners and overall crowd control especially when everything is at head height for some plasma bowling. Surge is the name of the name here with the secondary fire and hence the need for high crit rates and plays well with True Aim Solid staff to support your brain popping. 

Tac Psi Axe  - Rapid light spam at weak spots and general close threats working well with Malefic Momentum. Recommend an auto-swing for associated hand health risks. A solid way to get back emergency toughness also with Warp Expenditure. Great for lighter hordes, if any denser move backwards and switch to Voidstrike.
