Diablo – Can charmed monsters damage you

Each follower has a specific list of equipment he or she is capable of equipping. You can see this list by going to the items page on the official site and clicking the follower's icon at the top; here are quick links:

• Templar's items
• Scoundrel's items
• Enchantress' items

Regarding the special follower items, those are equipped in their own special slot and do not replace any other item. That slot is not immediately available, it is unlocked later in the game.

Yes, but there are some significant caveats.

1. Many pieces of gear affect how much experience you get from monsters. When comparing with others, you should remove all such gear.
2. There is still some debate about grouping with higher level heroes. I'll have more updates on that, in that question.
3. A monsters level depends on the difficulty level.
4. Remember that when your level changes (typically up), monster experience scales down.

There is a very helpful table here which lists the experience scaling for your level compared to a given monsters level. It is also untrue that you can't determine the level of a monster - but I don't think there is a way to determine it in game. I've also been taking measurements for other questions in various parties, and I've found the output to be consistent with the conclusion that monsters of the same level always award the same amount of experience.
