I think it could potentially be automated too, rather than IMM driven.

For example, if a solo Villager is trying to defend against a squad of Imperials perhaps he could ask the Destructor for support. The benefit could be dependant on how many Imperials are online, perhaps their PK ability (if Beront's Emperor turns up solo maybe you get it anyway) and if they're within PK (needs to be broad or people will solo the Giant to minimise the benefit).

As example the Destructor might "inspire you" and sing a few kick ass Bard songs. I'm sure his voice is lovely.

Maybe if a lone Imperial is trying to retrieve vs. a bunch of Forties, he could ask the Sect Leaders for support and get a black aura and resist holy/light for 24hrs. You would then NEED to try retrieve, not use it just to go out and PK an Outtie - this might require IMM overview to watch for abuse.

Maybe all of the above is only granted to committed players who actually stick it out through rough times, therefore mitigating the risk of abuse.

Not sure what the final solution is but I really like the concept.
