I think there might be some kind of misunderstanding, I’m not talking about escalation anymore, but what is and isn’t allowed for antagonists. There is no need to put these limits in the escalation rules as those are the domain of another rule.
Additionally, there doesn’t seem to be a difference between syndicate agents and thieves when it comes to handling steal objectives.
For example, from the specific rule :
Examples
Acceptable:
4 : Permanently round removing a single person so that you can impersonate them to make it easier for you to complete a steal objective.
6: Sabotaging a department’s power 10 minutes into the round to make a steal objective easier to accomplish. (Such as cutting the departments MV power, or removing/destroying the substation.)
7: Permanently round removing many people who have demonstrated a persistence and a capability to either kill you or interfere with the completion of your objectives.
(note that since thieves do have a pacifism implant, that implies that they could/would use violence to steal without it, like with explosives and chemicals items in there kits)
8: Killing an unrelated person in order to steal items held by said person, such as killing an engineer for their hardsuit and tools.
When an example is for a specific antagonist, it is specified, like with
3: Killing anyone you see while playing as nuclear operative(s).
or
9: As a traitor, buying a singularity attractor to guide the singularity to a kill target when it is already loosed.
I hope that these example help clarify what I meant, and that it is unwise to include antagonist specific limitation in the escalation rules, especially when they are contradictory to the antagonist specific rule.
