Wow thank you so much for all the feedback, that's really useful info! I've never seen a wand get that strong before in all my testing, pretty crazy! The reason the stronger rock gave you less damage was (probably) because it only had a single adjacency buff instead of a double adjacency buff. I think it's too hard to notice (because it was meant to be a whole different object if I had time), but the rocks can either buff the item in front, item behind, or both adjacent items. The ones that buff both are OP, lol.
Thank you so so much for playing my game and leaving such a wonderful comment, you have no idea how much I appreciate it (even seeing a screenshot made me squeal <3)
