the first option is to use a special melee weapon - neurazer. you have to go melee and use neurazer which will apply ‘paralysis’ UNTIL you see ‘paralized’ status update.
paralysis amount will drop per turn so you have to be careful and reapply if it wears of.
If you are Synedrion friend you will get access to a neural class of ranged weapons which also got paralysis damage. (check my topic: [BB5] [SPOILERS] Wiki / Manual. new classes, abilities, weapons and stuff - #2 by kane)
