Interaction options become unlocked depending on the amount of Experience points you have. Basically, the more Experience points you have the more interaction.
Stuff Stealing
If you make the Almeric crazy or scared with the potions then you can take his stuff and or eggs without him caring. I've done this and it's awesome do it a bunch of times. And give him a stamina potion if he gets tired or stuff like that. That way you can steal longer!
Unlimited Money Exploit
Start by making a donation at the church. The amount is irrelevant. Next, walk away from the donation plate and then click to donate again. While you are on your way back to the donation plate, cancel the queued donation task before you reach the plate. The amount of money you originally had donated will be returned to you. Continue to queue up the donate task and cancel it. Each time you cancel the task, you'll receive the amount you originally earmarked for donation.
