For pain: you’re on the right track trying not to aim for his teeth, but you were also on the right track trying to hit the tooth that hurts. Let me know if you need a more specific hint.
For deceit: did you talk to the hologram about it?
I need a more specific hint for pain. Thank you :)
For deceit: Yes to your question. I tried manipulating the cave painting, so the model for the god of deceit might resemble the "replica" but nope. Do I miss an item that I should have?
Pain: what if the pain is caused by a tooth, rather than being a toothache?
Deceit: you have all the objects you need. You only need to add something to the projection on the wall to make it look like the painting behind the bush.
