Zazy's Blazing Spirit Greatsword Unga Bunga Experience
 Psyker Build - Warhammer 40k: Darktide 

This is a full melee build, use of the Laspistol is typically reserved for melting bosses, tapping snipers or for triggering empathic to rush shooters when engaging in melee is not available

FORCE GREATSWORD:

 Sub 25% warp resistance is optimal, granting you ~50% peril on activation.  40% warp resist will still get you enough peril for max venting shriek soul blaze but anything higher will require 3 activations for critical peril from 0

PLAYSTYLE: I prefer mk6 fgs as warp slash combos directly into heavy stab, excellent for staggering elites and specials for a following kill stab.

 Light light -> block cancel loop or light light light -> block cancel loop is your best horde clear combo, choice between the two is preference, their DPS is the ~same.

FGS power gauge is ignored in this build as you will want to spam the special at every opportunity. your warp slash is your instant peril generation, ranged stagger and sniping tool for kinetic flayer.

 The build is extremely tanky and can heal straight through multiple rager combos while ramped up. 

The lack of keystones looks off-putting but the build maximizes uptime on every single buff to the point where your damage output is not hindered in any way.

The goal is to have your peril maxed out at all times so every peril talent is capped (warp rider, warp splitting, immaterial focus) and with 47.5 crit chance at full ramp all your crit talents also have 100% uptime (mettle, perfect timing, empathic evasion

Since this is a melee build with soul blaze and warp slash spam, both halves of malefic momentum are 100% capped out in combat

 Between your very high toughness DR, Empathic evasion, toughness regen on hit and toughness regen over time from warp expenditure, souldrinker and quietude (boosted by warp ghost) the build is extremely resistant to chip damage while engaged in melee

WARNING: VERY UNGA BUNGA, DO NOT RESIST

When run optimally you will have a near perfect 50/50 split between melee and ranged damage (warp slice, flayer, soul blaze) with high single target and spread damage at the same time while laspistol will give you top tier monstrosity damage with the builds high crit chance. Only sore point will be against crusher spam after their health buff

Not really recommended for havoc due to previously mentioned crusher spam hindering your ability to get stuck into melee brawls safely. Also hinders your fire spread when those chunky assholes stop all your cleave and keep all that soulblaze for themselves
