When I did it one could just not get a reaction by moving Idol to container. Honestly, it makes sense for Druids to accuse tieflings of theft when the idol disappears. I don’t mind it that much, though it kills me to have an incomplete quest. Like it feels there should be a way to steal the Idol without initiating genoside. The whole thing is kinda pointless though, as there doesn’t seem to be a time limit on the ritual (how does it trigger? I know it is possible for the ritual to complete). If there was a more interconnectivity and actual benefit to delaying the ritual the whole situation could be far more interesting.

About systemic stuff I like: environmental fire sources like candles being fire sources - so one can light grease with a candle. Makes me think - are all items coded with properties? Does metal in BG3 conduct electricity? Is there a more practical use for various items in BG3? I know D:OS2 had one pressure based puzzle that could be bypassed in unorthodox ways.
