We agree, Electrokinetic should be a single target focused staff.
The issue with Electrokinetic just gaining damage on attack is it’s high rate of fire, very strong stagger and strong aim assist (though the aim assist is inconsistent).
Balancing
To compensate for a buff like the one suggested below, stagger on hit should be reduced dramatically against Ogryns. After being staggered once, Ogryns should receive stagger immunity against Electrokinetic for a period of time. Also, base charge time with maxed out Charge Rate stat should be increased from .84 to 1.5s.
Damage
To give Electrokinetic stronger damage against single target and more consistent target acquisition, I believe it should receive the Brain Burst targeting mechanic with a similar visual cue indicating the current target - perhaps with an electrical flair. Upon releasing full charge, the bolt would seek the Weakspot.
Now Electrokinetic would also be able to hit weakspots and take advantage of those weakspot damage modifiers + powerful weakspot damage buff through DD (37.5% at 15 stacks). This would be a dramatic improvement to Electrokinetic damage output, and would allow it to enter 3 tap territory on Crushers with DD dedication (no Warp Charge + Shriek spam), and potentially 2 tap Crushers for very short bursts of time.
The Numbers:
Crit Stat maxed out:
Crusher Damage: 630/819/819/945
Boss Damage: 700/910/1183/1365
The following numbers are all based on the listed buffs below and the scenario in which a Psyker gets a Weakspot Crit hit (945 - Crusher, 1365 - Boss)
All Psyker damage buffs:
82.5 (Weakspot Crit hit at 15 DD stacks)
25 (5 stacks Malefic)
15 (5 stacks Perfect Timing)
30 (Unbound Scrier’s, 30 stacks)
30 (Precog Scrier’s, 30 stacks)
20 (Warp Rider, 75% Peril)
20 (Feeble Minds)
Total Possible: 225.5%
The stars are aligned for 10 seconds of Unbound, Scrier buffs have been maxed using Crack of Bone with melee…
Crusher Damage: 3,071 per full charge crit hit
Boss Damage: 4,436 per full charge crit hit
Now, not all hits will be crits, so the average actual damage would be a bit lower than these figures.
Realistically: 142.5%
(No Scrier’s buffs, <75% Peril, 15 stacks DD, Feeble Minds, Malefic, Perfect Timing)
Crusher Damage: 2,287 per full charge crit hit
Boss Damage: 3,303 per full charge crit hit
