i had a fire idea for a decaying winter forsaken killer. just an amalgam of the reikgons.

 for their first ability, their M1, 0.2 second windup, 1,5 second cooldown, 20 damage, +8 bleed, but has a smaller hitbox, & the hitbox lingers for much shorter.

for their second ability, this is part of their passive, so bear with me. the reikgon starts the match at a survivor spawn, shapeshifted into a random survivor. the reikgon cannot spawn at the same survivor spawn as the survivor they're shapeshifted into. when they reveal themself, they stop in place for 2.5 seconds, 4 seconds if the match hasn't gone on for 15 seconds or more. once the ability has been used at the start of the match, the reikgon can use this ability at will with a 30 second cooldown, shapeshifting into a random living survivor, but cannot choose which. the ability has a 1 second cooldown when shapeshifting, & a 30 second cooldown when revealing. 

for the third ability, the reikgon stops in place for 1 second, receiving invisibility 4 & undetectable 1. when getting within 30 studs of a survivor, the invisibility is reduced to 3, & within 5, it's 2. the reikgon can stab the survivor during this invisibility time period, if hitting them in the back, dealing 40 damage, but if hitting them in the front, dealing 20. the invisibility/undetectable lasts for 15 seconds total, & when stabbing the survivor, the invisibility/undetectable is revoked, & they return to their normal state. 

for their final ability, acting as the ESP ability, the reikgon stops in place for 3 seconds, forcing every survivor to stop in place as well, & mash E. after the reikgon gets out of endlag, every survivor is highlighted for 4 seconds. if the survivor fails to break out in 6 seconds, they take 20 damage. if the survivor breaks out in more than 4.5 seconds, they get speed I for 1 second. 

they have a passive where they are immune to all knockback from stuns/guest charge, unless the reikgon is in invisibility. reikgons are immune to shoves in DW. (excluding hidden)

the reikgon would have 700 HP, 110 stamina, 27.5 runspeed, 8.5 walkspeed, & 21 stamina regen per second.

is this a good concept or am i smoking something thinking this wouldn't be busted
