Plague Lich
 Psyker Build - Warhammer 40k: Darktide 

Plague Lich is a build that has a lot of advantages over other plague builds.. but i'm going to put this as gently as I can.. if you do not have absolute mastery over psyker move techniques and voidstrike casting techniques.. YOU CANNOT get away with playing this.. even for an exceptionally skilled psyker.. dueling sword is basically the minimum you can get away with.. Voidstrike absolutely requires combat blade if you're not running warp speed.. and if you're running dueling sword.. for most you would need at least warp speed.. I have the experience to get away with running dueling sword without warp speed on a Voidstrike build.. but at minimum it requires a defensive setup.. which is what this build runs in addition to warp speed to make it more fluid and to allow for effective weave casting. Voidstrike is extremely unforgiving if you don't have a minimum level of mobility.. and this build does achieve that with warp speed.. this build does have some serious advantages over the usual combat blade requirement.. this is the one of two Voidstrike builds I have that runs dueling sword.. it's basically a Plague Strike version of Electro-Lithe.. which is a VERY nice tooklit.. and instead of empowered Psionics.. you have Plague Strike combo casting to make up for it.. so this saves you points so you can run some nice shit that will ramp up dps. Dueling sword allows you to defensively kill anything pretty much and you're able to more easily deal with armour safely because of voidstrike combo casting + dueling sword.. MM stacks are easier to achieve as well with DS.. and you get to run ALL the high damage nodes as well.. Pokes with the mark 4 dueling sword ensure EASY MM stackage.. another advantage over dueling sword.
