Another comment about Pharaoh: In room P33, there are four grenade palms with explosive pineapple fruits. As written in this version, a fruit is guaranteed to fall if a creature comes within 5 feet of a palm. The fruit explodes with a 20-foot radius (which is the entire room and more!), dealing 6d6 damage! It talks about a creature being able to pluck a fruit off a tree safely with a Sleight of Hand check, but nothing about catching a falling fruit. There's also no mention of how many fruits each tree has on it.
Looking at the map, there's really no way to move around this room without triggering multiple explosive fruits.
I looked at the original. It doesn't mention how many fruits each tree has on it either, but it at least says there's only a 20% chance of a fruit falling. While there's a 95% chance it will explode when it hits the ground, it only does 2d8 damage in a 10-foot radius (covering only 1/4 to 1/2 of the room). There's also a chance a PC can catch a fruit, which reduces the explosive chance to 40%.
I know that 5e doesn't really do percent chances, but this might be one instance where it's worth reconsidering.
