the Psykers, Obscurus Mk II Blaze Force Sword’s special action is called Warp Charged.
when Warp Charged kills an enemy, It causes said enemies head to burst.
i feel this brain burst ability should generate a warp charge on kill.
this would allow the Psyker to have a more reliable way to generate Warp Charges in higher level play, as well as allowing them warp charges to be gained more seamlessly in combat.
right now if you want to guarantee a warp charge you have to pause your combat and switch to your brain burst ability, in later modes at harder difficulties this isnt viable as taking your self out of combat for 10 or more seconds can spell disaster for your team. not to mention if you hit it can take you out of the charge mechanic causing you to recharge and waste more time.
this would also allow the Force Sword to stand out against the Maccabian Mk IV Dueling Sword as it seems to be the weapon of choice for Psykers, with its fast strikes and multi target capabilities.
if this would cause some perceived imbalance that im not seeing this could be added in as a Blessing for the Obscurus Mk II Blaze Force Sword much like the Deflector blessing allowing the weapon more utility.
