To start off, this post is not all-inclusive, but merely aims to rework the base mechanics of Psyker’s abilities. The rest can follow as needed, but feel free to throw in any ideas as well. I would also like to stress ththe exact numbers of anything mentioned here are fluid, the important thing to carry across is the idea.
Blitz: Brain Burst
Left-click instantly casts the ability at your target, expending all Warp Charges and dealing damage based how many Warp Charges were consumed. Right-click charges Brain Burst and may be cast without consuming a Warp Charge, dealing one Warp Charge’s worth of damage.
Iconic: Warp Siphon
Whenever you kill an enemy, gain 5% of a Warp Charge. Whenever you kill an Elite or Specialist, gain 50% of a Warp Charge. If an ally in Coherency kills an Elite or Specialist, gain 25% of a Warp Charge. Each Warp Charge grants +3% damage. You can store up to 4 Warp Charges.
Level 15 Feat: Psychic Communion
Whenever an ally in Coherency kills an enemy, you gain 3% of a Warp Charge.
Level 15 Feat: Cerebral Lacerations
Reworked as Warp Discharge
Gain 1% of a Warp Charge for every 1% Peril Quelled.
Level 30 Feat: Quicken
Psykinetic’s Wrath expends all Warp Charges, increasing radius, stagger, and reducing Cooldown by 12.5% for each Warp Charge expended.
Level 30 Feat: Ascendant Blaze
Psykinetic’s Wrath expends all Warp Charges and applies Stacks of Soulblaze to Enemies Hit based on the number of Warp Charges expended.
Gain 2% of a Warp Charge whenever an Enemy dies with your Soulblaze effect (from any source).
Level 30 Feat: Kinetic Barrage
Reworked as Warp Overload
Psykinetic’s Wrath prevents Peril from rising for 10s.
You Brain Burst charges 25% faster. Brain Burst charged casts now deal damage equivalent to the number of Warp Charges.
Gain 0.75% Peril per second for each stored Warp Charge while not actively Quelling.
Your Perils of the Warp explosions deal damage scaling with the number of Warp Charges.
Notes
Someone on this forum before mentioned the idea of consuming Warp Charges for Brain Burst. This post runs with that idea, and then some.
As stated, this does not cover every facet of the Psyker’s arsenal that would have to be changed in order to effect this rework, but it does include some of the more important Feats to go along with it. The exact numbers of anything mentioned here are fluid, the important thing to carry across is the idea.
The general idea of this rework was to give Warp Charges a purpose other than to be hoarded. They no longer decay, and while they still provide a passive effect, their main purpose is as currency to instantly cast a more powerful Brain Burst. The idea is to incorporate the gaining and losing of Warp Charges as part of regular gameplay, and that just keeping it at max stacks is not necessarily the most optimal way to play.
Brain Burst
Brain Burst received a lot of changes. Left-click instantly casts the ability, consuming all Warp Charges and dealing damage based on how many it consumed, with the same Peril cost. You can still charge up a Brain Burst like usual if you see no reason to spend your stacks on that target, or have none, but damage will remain at a base level - unless you’ve got Warp Overload, more on that below. I leave the exact numbers on Brain Burst damage and it’s Warp Charge scaling to better people, but safe to say it should follow a series of breakpoints.
Warp Siphon
Speaking of, how you gain Warp Charges has changed, and the Warp Siphon Iconic by extension. You now gain percents of a Warp Charge whenever you fulfill a certain requirement - by default, whenever you kill an enemy, Elite or Specialist, or when allies in Coherency kill an Elite or Specialist. This can be modified through various Feats, like the changed Psychic Communion, the new Warp Discharge, Ascendant Blaze, or others. This eliminates some dependency on personal kills by the Psyker player, and also removes a heavy RNG factor.
Level 30 Feats
The Level 30 Feats also received some changes. Quicken has increased radius and stagger in addition to cooldown reduction for each Warp Charge consumed, while Ascendant Blaze has had some much-needed QOL done to it.
Then there’s Warp Overload, the replacement for Kinetic Barrage. This is the live-fast-die-hard talent that turns your Warp Charges into Warp Grenades - with the pin lost and the spoon already flying through the air. Charged Brain Bursts scale in damage the same as instant cast and don’t consume Warp Charges, but at tremendous cost - you’re constantly fighting the buildup of Peril, both passive buildup and through Brain Burst. Do you want to take Warp Battery for 6 charges and yet greater damage and danger, or Mind In Motion so you can move and Quell at the same time? At least when you inevitably blow up, you’ll take your enemies to Hel with you. Choices, choices.
Overall I feel like this design makes for more meaningful choices and gameplay paths than before, not to mention Psyker being just more fun to play.
