Sorry if posted or asked could find anything on this via search.

So as stated puppet master can target a vehicle eg. Defiler, if so, would it be able to shoot all of its weapons or pick one. since "a shooting attack"

Also how would it be resolved if used on another Psyker? If you wanted to use other players psker shooting attack. Alowing me acces to spells/Discipline that arn't available to Eldar. Irony of burnning them with their own Pyromany if you will.
EG, Farseer with Runes of Ward, useing puppet master on Deamon Prince/ lash or other spell.
Forceing other players Psyker to take Wounds via Perils of the warp or use lash/other spell on his own army.

My psy test. target players model 2D6
Deny witch roll
then psy test on their model RoW=3D6
target unit
deny witch roll
move unit out of threating, scoring, or in range for assaulting (lash)
Seems like alotta testing but I want to force Psyker to suffer Perils of Warp for those who are scared to use their powers due to RoW and take a wound(s) before they get into assault.
