what about adding this to ckit and also some low DPS
its range must be short
effect can be poison like. draining both some hp and stamina over time
and effect of stamina loss must be a slight slow down
edit:
damage: 20
(0, 4, 6, 7 , 3) over 5 seconds
if boosted target gets the first 4 dmg, it stops but target loses boost
reload: 5 seconds
ammo: inf
range: same as overmind attack range
effect on speed: reduced by 0.15 for 5 seconds
