Everyone inside of the Inquisitorius Order that wishes to make it far need to be trained in the art of interogation. It is a requirement to be interogation trained to pass Adept trials. The rebals have secrets and we are the ones to get the truth from them.
When interogating a prisoner it is best to use everything at your disposal and dont be afraid to RP some aspects instead of just wacking them with your saber. It is important to note you have to role after trying an interogation tactic (/role). Some notable examples of tactics you coiuld use would be:
Using the force to inflict nightmares
cause hallusinations
Use the force to inflict harm
and much more
As Inquisitors we are masters of the dark side and as such have a wide library of force powers to pick from. Some of these force powers are more useful and can be used in interogations notable examples are:
Force Combust - light opponents ablaze
Electric Judgement - Blind and Stun enemies
Force Blind - Forcefully blind opponents
Force Choke - Choke your opponents
Force Stasis - Completly Stop your opponents in their tracks
It's important to be creative in interogation and have a fun time. The only limit to what you can do is your own imagination while keeping everything in line with the servers rules and regulations.
