This build was designed with supporting your team as efficiently as possible. The weapons of this build can be altered to better suit your playstyle. The Blaze Sword is a strong option. With this build, you may not be getting many kills, but using your blitz ability to stun lock the entire screen will be immeasurable to your teams success. In addition, this build uses the dome shield ability, to protect your team from ranged assault and to regain toughness. Use this skill freely to protect your team whenever needed. You’ll want to stick with your team throughout the mission, while your not weak, your abilities shine best when you allies are able to capitalize on the advantage given to them.
The Dueling Sword is a great precision weapon, capable of fast, accurate strikes. This is a great weapon that is able to perform against both hordes and elites alike.
Precognition and Riposte perks both activate off of dodging. For the first perk, getting Finesse will increase your attack speed, for a weapon that is already very fast, this makes is very viable to deal with hordes. Riposte is ideal for dealing with Elites/Specials, the increased critical strike chance is a huge help for these tougher enemies. It has a pretty long duration as well with 6s total duration.
For modifiers, Maniacs or Flak is ideal to cover a wide range of enemy types. More melee critical hit chance is great to have and benefits the weapon greatly.
The Voidstrike staff is easily considered one of the best staffs available for the Psyker. It has great attacks, both charged and uncharged, able to deal with hordes and tougher enemies.
Surge is a simple perk that will fire 2 shots on critical hits rather than one, doubling your damage. This applies for both charged and uncharged attacks. Transfer Peril helps keep your peril under control, allowing for more attacks before you need to quell or swap to your sword.
Maniac of Flak will cover many enemy types, and Unyielding will help against tough enemies, and monstrosities.
Curios are really flexible, with only a couple perks that really benefit builds. In this case, Health can be substituted for Toughness if required, but health is still recommended. You will want at least 1 Curio to have 1 Wounds on it, wounds increase the amount of health bars you have. This is beneficial, especially on higher difficulties, as it allows some leeway if mistakes happen, or you get overwhelmed.
Stamina Regen is really important and should be the only modifier you go for one each Curio you use. Block Efficiency is great to have to further extend the capabilities of your melee weapon. Block Efficiency or Corruption Resistance are both useful for their own reasons. If you want a more generalized experience, use more Block Efficiency.
