I wonder If it’s possible to do ”attack” worship - if a god cannot resist worship, you might be able to make some kind of ”injection attack” using deliberately misconstrued worship. You might sacrifice inappropriate stuff, perform sabotaged rituals, recite made-up myths, or perhaps the MPs you sacrifice might be tainted (chaotic, originating from inappropriate sacrifices, and so on)?
The god won’t be the least bit happy about this, but as you’re probably some kind of Illuminate, God Learner or other actor capable of defending yourself against Agents of Reprisal if you’re doing this kind of thing, that might not be enough to stop you.
I mean, what does happen if you perform human sacrifices to Chalana Arroy, and can handle the divine defences? Could you generate, at least locally, “Bloody-Handed Chalana”?
